If the seat adjustment does not allow the driver to reach the necessary height for proper visibility, is it permitted to use a cushion or booster?

Question

DentroTest · Accepted Answer

Yes, it is permitted. A correct driving posture is fundamental for safety and vehicle control. If the driver is short and the seat does not offer sufficient height adjustment, a booster may be used. The rule establishes a vital safety condition: the booster must be firmly attached to the seat. Why is this important? If the cushion or booster is left loose, there is a serious risk of the 'submarine effect' occurring in the event of an accident or sudden braking. This means the driver's body could slide under the lap belt of the seatbelt, causing serious internal injuries or strangulation, and nullifying the effectiveness of the restraint system.
