Division 2.2.1.6

On vehicles with a maximum design speed not exceeding 30 km/h, the service braking system shall act on all the wheels of at least one axle. In all other cases the service braking system shall act on all the wheels of the vehicle. However, in case of vehicles with one braked axle and an automatic engagement of the drive to all other axles during braking, all wheels are deemed to be braked.

For category C vehicles this condition is considered to be met if all of the track rollers of the vehicle are braked. For category C vehicles with a design speed of less than 30 km/h, this condition is considered to be met if at least one track roller on each side of the vehicle is braked.

For vehicles equipped with a straddle seat and handlebars, the service braking may act either on the front axle or on the rear axle provided that all the performance requirements prescribed in point 2 of Annex II to this Regulation are met.

For articulated tractors of category Ta, if an axle is subject to braking and the differential is mounted between the service brake and the wheels, all wheels of that axle are deemed to be braked when the activation of the service braking system automatically locks the differential on this axle.
