CBR Bus Theory D flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Right-hand priority rule

At an unsignposted junction, traffic coming from the right has right of way. This does not apply when leaving a driveway, parking area or unpaved road onto a paved road.

Built-up area speed limit

Within the built-up area (between the place-name sign and the end-of-area sign) the default maximum speed is 50 km/h unless signs show a lower limit.

Motorway night speed limit

On Dutch motorways the limit is 100 km/h from 06:00 to 19:00 and 130 km/h from 19:00 to 06:00, unless signs show a lower limit.

Yellow traffic light meaning

A yellow (amber) light means stop, unless stopping would cause danger. A flashing yellow light means the general rules for unsignposted junctions apply.

Priority road sign

A yellow diamond with a white border marks a priority road. Traffic on it has right of way over traffic from side roads until the end-of-priority sign.

Overtaking on the right

Overtaking on the right is forbidden, except in slow-moving queues in separate lanes, when the vehicle ahead signals a left turn, or when passing a tram.

Bus maximum authorised mass

A two-axle bus may weigh at most 18 tonnes; a three-axle bus at most 25 tonnes. Articulated buses may weigh up to 28 tonnes.

Bus tyre tread depth

Vehicles over 3.5 tonnes, including buses, must have at least 1.0 mm tread depth across the central three-quarters of the tyre.

Air brake low pressure warning

If air-brake pressure falls below about 4.5 bar, a warning must sound. The spring parking brake then applies automatically, so the vehicle fails safe.

Door interlock function

The door interlock prevents the bus from driving off while a passenger door is open. Check the warning lamp and alarm before moving away.

Retarder on slippery roads

The retarder or engine brake must be switched off on slippery surfaces because it can cause the driven wheels to skid. ABS and ESP stay on.

Two-second following rule

Stay at least two seconds behind the vehicle ahead. Double this to four seconds in rain, at night, or when following a large vehicle.

Braking distance and speed

Braking distance increases with the square of speed. Doubling your speed quadruples the braking distance needed to stop.

Bus blind spot areas

A bus has large blind areas directly in front, at the right front corner and along the right side. Scan the mirrors every five to eight seconds.

Rear fog light rule

Rear fog lights may only be used when visibility is less than 50 metres. Using them in rain or light fog dazzles following drivers.

Daily driving limit

A driver may drive at most 9 hours per day, extendable to 10 hours twice per week. The weekly maximum is 56 hours.

Four-and-a-half hour break

After 4.5 hours of continuous driving the driver must take a 45-minute break, which may be split into 15 minutes followed by 30 minutes.

Reduced daily rest

Daily rest is normally 11 hours. It may be reduced to 9 hours at most three times between two weekly rest periods.

Weekly rest compensation

A reduced weekly rest of at least 24 hours must be compensated by an equivalent rest taken en bloc before the end of the third following week.

Tachograph record retention

The driver must be able to show the last 28 days of tachograph records plus the current day. Enforcement officers may check up to 56 days.

Wheelchair securing on bus

A wheelchair must be secured with a four-point strap system, its brakes applied, and the occupant restrained with a three-point belt where fitted.

Bus evacuation procedure

Stop safely, switch off the engine, apply the parking brake, open the emergency exits, lead passengers away from traffic, then call 112.

DRABC first aid sequence

DRABC stands for Danger, Response, Airway, Breathing, Circulation. Check each step in order before starting resuscitation or calling for help.

CPR compression rate

Chest compressions for an adult are given at 100 to 120 per minute, pressing 5 to 6 centimetres deep, allowing full chest recoil.

Bus maximum dimensions

An EU bus may be at most 2.55 m wide and 4.0 m high. A rigid bus may be 12 m long, an articulated bus 18.75 m.

Load securing requirement

Load must be secured so it cannot shift or fall, and must not obscure lights, mirrors, plates or the driver's view of the road.

APK inspection interval

Buses used for passenger transport must pass the periodic technical inspection (APK) every year. The valid certificate must be carried in the vehicle.

Warning triangle distance

Place the warning triangle at least 30 metres behind the vehicle on normal roads and about 100 metres behind on motorways.

Emergency call information

When calling 112, give the exact location, number of casualties, type of incident, hazards present such as fire or fuel, and your callback number.

Motorcyclist helmet removal

Do not remove a motorcyclist's helmet unless the airway is blocked. Support the head and neck and wait for the ambulance crew.

Burn treatment

Cool a burn with lukewarm running water for at least ten minutes. Do not remove clothing stuck to the burn or apply ointments.

Shock casualty position

Lay a shocked casualty flat, raise the legs if there is no fracture, keep them warm, and give no food or drink.
