32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Default urban speed limit
- In Alberta, the default maximum speed on urban roads is 50 km/h unless a sign indicates otherwise.
- Two-second following rule
- In ideal conditions, a driver should stay at least two seconds behind the vehicle ahead; increase to four seconds on ice, snow, or wet roads.
- Uncontrolled intersection right of way
- At an intersection with no signs or signals, the vehicle on the right has the right of way; a left-turning vehicle must yield to oncoming traffic.
- School zone speed
- School zones in Alberta are 30 km/h during posted times; playground zones are 30 km/h from 8:30 a.m. until one hour after sunset unless posted otherwise.
- Solid yellow line meaning
- A solid yellow line on your side of the road means passing is prohibited; it is often used on curves, hills, and where visibility is limited.
- Zero alcohol tolerance for novices
- Graduated driver licensing rules in Alberta impose a zero blood alcohol limit for novice drivers; any alcohol is a violation.
- Emergency vehicle response
- When an emergency vehicle approaches with lights and siren, pull to the right and stop; on a one-way road, yield to the nearest curb.
- Child restraint requirement
- Children under six years old and weighing less than 18 kg must be secured in an appropriate child restraint when riding in a vehicle in Alberta.
- Railway crossing stop distance
- At a railway crossing with flashing lights, gates, or a stop sign, stop at least 5 metres from the nearest rail and proceed only when safe.
- Pre-trip inspection items
- A pre-trip inspection must check lights, tires, brakes, steering, mirrors, windshield, wipers, horn, coupling devices, and cargo securement before driving.
- Daily trip inspection report
- Commercial drivers must complete and sign a daily trip inspection report, record any defects, and report defects to the carrier before driving.
- Static air leak test limits
- With the engine off and brakes released, air pressure loss must not exceed 3 psi per minute for a single vehicle or 4 psi per minute for a combination.
- Low-air warning threshold
- A low-air warning must activate before system pressure drops below 60 psi; spring brakes apply automatically at about 20 to 45 psi.
- Hours of service limits
- In Alberta, a commercial driver must not drive after 14 consecutive hours on duty and is limited to 13 hours of driving per day.
- Minimum tire tread depth
- Commercial vehicles must not operate with tires having less than 1.6 mm (2/32 inch) tread depth or with visible cord or sidewall damage.
- Fifth-wheel pull test
- After coupling, apply the trailer brakes and pull gently against them to confirm the fifth-wheel jaws are locked before driving.
- Load securement recheck interval
- Drivers must inspect cargo securement within the first 80 km and every 3 hours or 240 km thereafter, and after any load change.
- Air brake operating pressure
- Air brake systems normally operate at 690 to 830 kPa (100 to 120 psi); the compressor recharges the system when pressure drops below the cut-in pressure.
- Dual-circuit air brake system
- A dual-circuit system has two separate air circuits so that a failure in one circuit still leaves braking capability in the other circuit.
- Spring brake operation
- Spring brakes are held applied by mechanical springs and released by air pressure; they apply automatically when pressure falls to about 20 to 45 psi.
- Tractor protection valve function
- The tractor protection valve closes to prevent air loss from the tractor if the trailer breaks away or the trailer air line fails.
- Slack adjuster pushrod travel
- The slack adjuster converts pushrod motion into brake application; pushrod travel must not exceed the manufacturer's limit, typically 51 mm (2 inches) for a type 30 chamber.
- Air system build-up test
- With the engine at operating speed, the air system must build from 85 to 100 psi within 45 seconds at idle to confirm the compressor is working.
- Air dryer purpose
- The air dryer removes moisture from the compressed air system; moisture can freeze in lines and cause brake failure in cold weather.
- Maximum gross vehicle weight
- Alberta's legal maximum gross vehicle weight for a combination is 63,500 kg, subject to axle and tire limits; single axles are typically limited to 9,100 kg.
- Overhang warning flag requirement
- Loads extending more than 1.5 metres beyond the rear of a vehicle must have a red flag or light attached to warn other drivers.
- Load centre of gravity
- Cargo should be distributed to keep axle weights legal and the centre of gravity low and centred to maintain vehicle stability.
- Driver responsibility for overload
- The driver is responsible for ensuring the vehicle is not overloaded and that the load is properly secured before driving; overloaded vehicles can be ordered off the road.
- Dangerous goods documentation
- When transporting dangerous goods, the driver must carry required documentation, display placards, and follow the Transportation of Dangerous Goods Act and Regulations.
- Aggregate working load limit
- Tiedown devices used to secure cargo must have an aggregate working load limit of at least 50% of the weight of the cargo being secured.
- Trailer towing limit
- A vehicle must not tow more than one trailer unless specifically permitted; the towing vehicle must have adequate braking and hitch capacity.
- Spilled load cleanup duty
- Drivers are responsible for cleaning up any cargo that falls from their vehicle and for preventing spilled material from becoming a road hazard.
