Safety risks include incorrectly adjusted headlamps. If they are set too low, they create poor visibility for the driver. Lights that are set too high can lead to extreme glare from oncoming traffic and cause serious accidents. The tread depth of the tires is an important safety factor. Worn tires have a much longer braking distance on wet roads. The legally prescribed tread depth of 1.6 millimeters is not sufficient in terms of safety. At this tread depth, the risk of aquaplaning is already very high. With aquaplaning, the vehicle slips uncontrollably.
