24.Road Testing

📋

Road Test Components and Structure

general

All road tests consist of a pre-trip inspection, an air brake pre-trip inspection (if equipped with air brakes), and a road test. You must demonstrate a pre-trip inspection (with written report), basic vehicle control skills, and handling in traffic. A Class 1 road test takes about two hours; Class 2, 3, 4 and heavy trailer endorsement tests take less than two hours.

Key Rules
  • All road tests include a pre-trip inspection and an air brake pre-trip inspection if the vehicle is air-brake equipped
  • A Class 1 road test takes about two hours
  • Arrive at least 15 minutes early and provide 48 hours notice or a valid reason to avoid a no-show fee
🛑

Pre-Trip Inspection Test Requirements

airbrakes

The National Safety Code requires most commercial drivers to complete trip inspections. Applicants for Class 1, 2, 3, 4, heavy trailer, house trailer, or air brake endorsement must conduct a pre-trip inspection. Class 1, 2, 3 or 4 unrestricted applicants must also complete a written trip inspection report. Pre-trip inspections must always be done before the first run of the day.

Key Rules
  • Under the NSC, pre-trip inspections must always be done before the first run of the day
  • Class 1, 2, 3 or 4 unrestricted licence applicants must complete and submit a written trip inspection report
  • Vehicles with manual slack adjusters require a brake adjustment as part of the test
🚛

Road Test Skills Demonstration

combination

During your road test you must competently demonstrate: starting and stopping, shifting gears, turning, steering, backing up, parking, merging with highway traffic, exiting highways, driving in traffic, and coupling/uncoupling a tractor from a trailer (Class 1 or heavy trailer endorsement code 20). Concentrate on traffic, not on what the examiner records.

Key Rules
  • Coupling and uncoupling a tractor from a trailer is required for a Class 1 road test or heavy trailer endorsement (code 20)
  • You must demonstrate all basic control skills including backing up, parking, merging, and exiting highways
📋

Automatic Transmission Restriction

general

If you take your Class 1, 2 or 3 road test using an automatic transmission, your licence will be restricted to automatic transmissions only. This is an important consideration when selecting your road test vehicle.

Key Rules
  • Taking a Class 1, 2 or 3 road test with an automatic transmission restricts your licence to automatic transmissions only

25.Heavy Vehicle Braking

🛑

Anti-lock Braking System (ABS) Basics

airbrakes

ABS does not allow you to drive faster or stop sooner. On some surfaces such as gravel, braking distance with ABS may actually be longer. ABS helps prevent wheel lock-up on slippery surfaces, allowing you to brake hard without skidding or losing steering control, and may help prevent jackknifing. ABS is only as good as the driver — learn and practise the correct technique.

Key Rules
  • ABS does not let you drive faster or stop sooner; on gravel braking distance may be longer
  • ABS prevents wheel lock-up so you can brake hard without losing steering control
  • Read the vehicle manufacturer's manual to learn to use ABS properly
🛑

Emergency Stopping with ABS

airbrakes

When making an emergency stop with ABS, apply firm, hard continuous pressure to the brake pedal until the vehicle stops. Do not pump the brakes as this turns the system on and off. Brake noise, pedal movement or shudder is normal — keep applying firm pressure. Be extremely cautious steering around obstacles as handling depends on size, load and trailer.

Key Rules
  • Apply firm, hard continuous pressure to the brake pedal until stopped
  • Do not pump the brakes with ABS
  • Do not be alarmed by brake noise, pedal movement or shudder — keep firm pressure applied
🚛

Jackknifing

combination

A full jackknife occurs when a tractor and the trailer form an angle of 90 degrees or less relative to one another. This can happen even at very low speeds. Jackknifing is often caused by poor braking techniques, including improper use of retarders.

Key Rules
  • A full jackknife is when tractor and trailer form an angle of 90 degrees or less
  • Jackknifing can occur even at very low speeds
  • Jackknifing is often caused by poor braking and improper retarder use
📋

Why Heavy Vehicles Take Longer to Stop

general

A heavy tractor-trailer can weigh up to 63,500 kg loaded. Stopping a tractor-trailer at 100 km/h in an emergency (about 7 seconds) requires a stopping force of nine times the acceleration force — approximately 4,000 hp. Each brake on an 8-axle 16-brake vehicle provides about 1/16 of the braking force. If brakes are out of adjustment or axles unequally loaded, others work harder, increasing stopping distance and heat buildup.

Key Rules
  • A loaded tractor-trailer combination can weigh up to 63,500 kg
  • Out-of-adjustment brakes force other brakes to do more than their share, increasing stopping distance
  • Unequally loaded axles may cause lighter-loaded wheels to skid
  • Excessive brake use can cause heat buildup exceeding what brakes can dissipate, leading to failure
🛑

Total Stopping Distance and Time

airbrakes

Total stopping is a see-think-do process. It includes perception time (see-think, about 3/4 second), reaction time (do, about 3/4 second), brake lag time, and braking time. Air brakes have a brake lag time of approximately 4/10 of a second between application and function, unlike cars where brakes work almost instantly.

Key Rules
  • Total stopping time = perception time + reaction time + brake lag time + braking time
  • Air brakes have a brake lag time of approximately 4/10 of a second
  • Average driver's perception time is about 3/4 second and reaction time about 3/4 second
  • Stopping time is longer if brakes are incorrectly adjusted or vehicle is on a downgrade
📋

Following Distance for Heavy Vehicles

general

Passenger cars use the two-second rule. Drivers of buses, trucks and other large heavy vehicles should never be less than five seconds behind the vehicle ahead at highway speeds. Stay even further back when conditions are less than ideal.

Key Rules
  • Heavy vehicle drivers should never be less than five seconds behind at highway speeds
  • Passenger cars and light trucks use the two-second rule
  • Stay even further back when conditions are less than ideal
📋

Effects of Speed and Weight on Stopping

general

Speed and weight affect stopping power required. Doubling vehicle speed requires 4 times the stopping power. Doubling vehicle weight requires 2 times the stopping power. Doubling both speed and weight requires 8 times the stopping power. Road grade also matters — downhill requires longer stopping distance, uphill shorter.

Key Rules
  • 2 x vehicle speed requires 4 x the stopping power
  • 2 x vehicle weight requires 2 x the stopping power
  • 2 x speed and 2 x weight requires 8 x the stopping power
  • Going downhill requires longer stopping distance due to gravity
📋

Brake Heat Limits and Brake Fade

general

In normal stopping brake components heat to about 120°C, and can handle up to about 250°C under hard braking. Excessive heat causes drums to expand away from linings, resulting in brake fade, damage or failure. Brake components or tires may catch fire. Brake fade occurs when overheated brakes stop working properly, causing longer or no stopping.

Key Rules
  • Brake components operate best at around 120°C and should not exceed 250°C
  • Too much heat causes brake fade, brake damage or brake failure
  • Brake fade occurs when brakes overheat and stop working properly
  • As brake drums heat up, they expand away from the brake linings
📋

Descending Downgrades Safely

general

Most brake failures and runaway crashes are caused by overdriving brakes' ability to handle heat (poor speed control). Descend a hill more slowly than other traffic. Be in a lower gear going down than used to climb. Never shift to a higher gear on a downgrade unless speed can be controlled with a retarder or engine compression. Select a safe speed for weight, length, steepness, weather and conditions.

Key Rules
  • Be in a lower gear to go down a hill than used to climb it
  • Never shift to a higher gear on a downgrade unless speed can be controlled by retarder or engine compression
  • Almost all brake failures and runaway crashes are caused by overdriving brakes (poor speed control)
  • Control speed so you can stop at any time for an emergency while descending
📋

Downgrade Braking Procedure on Highways

general

If your chosen safe speed, low gear, and retarding device don't control speed and it increases, apply the brakes hard enough to reduce speed by 10 to 15 km/h while brakes are cold, then downshift to a lower main gear (don't use the splitter valve). Continue using engine compression, gearing and retarder. Repeat if needed. Use four-way flashers and stay in the far right lane.

Key Rules
  • Apply brakes hard enough to reduce speed by 10 to 15 km/h when brakes are cold
  • Downshift to a lower main gear (don't use the splitter valve on a downhill)
  • Use engine compression, transmission gearing and retarding device to control speed
  • Keep your vehicle in gear all the way down the hill
  • Use four-way flashers and stay in the far right lane where possible
🚛

Combination Unit Braking

combination

With air brakes, all brakes apply at the same time and same pressure when you step on the pedal. Applying brake pressure too forcefully or only trailer brakes on slippery roads may cause wheel lockup, skid or jackknife. Use extra caution in curves. Brakes, tires and suspension work best when legally loaded and load properly distributed. Empty cargo without ABS may cause wheel bounce and lockup.

Key Rules
  • With air brakes, all brakes apply at the same time and same pressure
  • Applying trailer brakes only on slippery roads may cause a skid or jackknife
  • Use extra caution when applying brakes in a curve
  • Empty cargo area without ABS may cause wheels to bounce and lock up
  • Towing two trailers requires extra care as they are difficult to stop in a straight line
🛑

Anti-Lock Braking Systems (ABS)

airbrakes

ABS is mandatory in Canada on all trucks and buses over 4,560 kg manufactured since April 1, 2000, and on all commercial trailers equipped with air brakes. ABS is an addition to a normal air brake system that helps prevent wheel lockup or skids caused by overbraking on slippery surfaces.

Key Rules
  • ABS is mandatory on trucks and buses over 4,560 kg manufactured since April 1, 2000
  • ABS is mandatory on all commercial trailers equipped with air brakes
  • ABS is an addition to a normal air brake system
  • ABS helps prevent wheel lockup or skids from overbraking on slippery surfaces
🚛

ABS in Combination Vehicles

combination

When operating combination vehicles, make sure you know which units have ABS. If the tractor and trailers do not all have ABS, apply the brakes as if you were operating a combination without ABS.

Key Rules
  • Know which units of a combination have ABS
  • If not all units have ABS, brake as though operating without ABS
🛑

Automatic Traction Control (ATC)

airbrakes

ATC is an optional addition to an ABS system. It uses the pulsating signal from the ABS wheel speed sensors to detect loss of drive wheel traction on slippery surfaces. If a drive wheel begins to spin, ATC applies that brake, transferring power to the opposite side. In extremely slippery conditions, ATC reduces engine power to let wheels regain traction. Vehicles with ATC have a dash information decal and dash-mounted warning lamp.

Key Rules
  • ATC uses the same wheel sensors as ABS to detect drive wheel spin
  • ATC applies the spinning wheel's brake to transfer power to the opposite side
  • In extremely slippery conditions ATC reduces engine power to restore traction
📋

Basic Scientific Principles of Braking

general

A brake is a heat conversion machine that works opposite to an engine. Brakes convert the energy of motion into heat energy through friction between brake drums/rotors and brake linings/pads. The heat is absorbed and dissipated into the atmosphere primarily through the brake drums/rotors. Braking effectiveness depends on the linings/pads producing friction, drums dissipating heat, and tires gripping the road.

Key Rules
  • Brakes convert the energy of motion into heat energy through friction
  • Heat is dissipated primarily through the brake drums/rotors
  • Braking depends on friction between lining/pad and drum/rotor surfaces
  • Bald or defective tires may degrade braking performance
📋

Retarders and Their Use

general

Retarders provide auxiliary slowing for controlling speed on long downgrades without the main braking system, saving brakes for emergencies. Four types: engine, exhaust, hydraulic driveline, and electric driveline retarders. An engine retarder is more efficient at higher engine r.p.m. and lower vehicle speed — select the right gear before starting downhill. Be cautious on slippery roads as retarders can lock drive wheels and cause jackknifing.

Key Rules
  • The four types are engine, exhaust, hydraulic driveline and electric driveline retarders
  • Engine retarders are most effective at higher r.p.m. and with transmission in low gear
  • Select your gear before starting down a hill, not on the downgrade
  • Retarders on slippery roads can lock drive wheels and cause loss of control or jackknife
  • Obey signs restricting the use of engine retarders/engine brakes
📋

Safe Braking Technique

general

Bring a vehicle to a stop on level roadway by squeezing gradually and firmly on the brake pedal. Just before a full stop, reduce brake pressure to prevent jerking back. To stop safely, ensure brakes are correctly adjusted, load balanced, and tires in good condition and properly inflated. Travel at a speed allowing you to see ahead and maintain safe following distance.

Key Rules
  • Squeeze gradually and firmly on the brake pedal to stop
  • Reduce brake pressure just before a full stop to prevent jerking back
  • Ensure brakes are correctly adjusted, load balanced, and tires in good condition
  • Make stops slowly to give the driver behind plenty of notice
📋

Braking on Icy Roads

general

On icy roads use extremely light pressure on the brake to control speed and prevent wheels from locking up. A slowly revolving wheel is more effective than a locked skidding wheel. Vehicles with ABS require a different technique. Use snow tires and/or chains; mount chains in designated chain-up areas before steep hills. Reduce speed when driving with tire chains.

Key Rules
  • Use extremely light brake pressure on icy roads to prevent wheel lockup
  • A slowly revolving wheel is more effective than a locked skidding wheel on ice
  • Mount tire chains in designated chain-up areas before steep hills
  • Don't deflate tires to install tire chains; reduce speed when driving with chains
📋

Water on Roadways and Brakes

general

Water can reduce braking efficiency. Avoid driving through large amounts of water when possible. If you must, cover the brake pedal and place a slight constant drag on the brakes while driving through to reduce water entering the drums and shoes. Reduce speed before driving through water. After driving through water, test brakes by applying slight pressure to dry them out.

Key Rules
  • Reduce speed before driving through large pools of water on the roadway
  • Apply a slight constant drag on brakes while driving through water
  • After driving through water, apply slight brake pressure to dry out the brakes
  • Water can reduce braking efficiency
📋

Runaway Lanes

general

Runaway lanes are located beside the road on some downhill grades to help slow and stop vehicles whose brakes fail while going downhill. They should be used only to control your speed or stop, not for any other purpose.

Key Rules
  • Runaway lanes help slow and stop vehicles whose brakes fail on downhill grades
  • Runaway lanes should be used only to control your speed or stop
  • Don't use runaway lanes for any other purpose
🛑

Fines for Improper Brake Adjustment

airbrakes

You can be fined as much as $2,000 if operating a vehicle with brakes that are not adjusted correctly or not performing adequately. The most common air brake defect found during inspections is brakes out of adjustment.

Key Rules
  • You can be fined as much as $2,000 for operating with incorrectly adjusted brakes
  • The most common air brake system defect found during inspection is brakes out of adjustment
