Once the passenger car has reached 85 ± 2 km/h, the brakes are always activated at the same place on the test track referred to as “braking starting point”, with a longitudinal tolerance of 5 m and a transverse tolerance of 0,5 m.

Controlling the vehicle; taking into account: proper use of safety belts, rear-view mirrors, head restraints; seat; proper use of lights and other equipment; proper use of clutch, gearbox, accelerator, braking systems (including third braking system, if available), steering; controlling the vehicle under different circumstances, at different speeds; steadiness on the road; the weight and dimensions and characteristics of the vehicle; the weight and type of load (categories BE, C, CE, C1, C1E, DE, D1E only); the comfort of the passengers (categories D, DE, D1, D1E only) (no fast acceleration, smoothly driving and no hard braking) ...[+++];

1.1. 2 braking, ABS, retarder, speed governor: operating principles, specific features of hydraulic vacuum servobrake circuit, limits to the use of brakes and retarder, combined use of brakes and retarder, use of braking systems on different types of road and under different atmospheric conditions, stopping and braking distance, making better use of speed and gear ratio, making use of vehicle inertia, using ways of slowing down and braking on downhill stretches, effects of weights and dimensions, controls and checks which are the responsibility of the driver, action in the event of failure;

After each stop, the vehicle must immediately be subjected to maximum acceleration to reach the initial test speed and maintained at that speed until the initiation of the next stop.
