Flying sheets of ice Dangerous ice sheets on truck

Every winter, ice or snow on vehicle roofs can cause dangerous situations or even serious accidents. Several hundred litres of water can collect on truck bodies and freeze. Trucks with tarpaulin roofs are particularly affected.

For passenger cars, seeing and removing snow and ice does not pose any great problem. However, considerable difficulties are involved when it comes to trucks. This is particularly the case when snow and ice layers are thin, as they are often difficult to see.

Sheets of ice that come loose from vehicle roofs can become dangerous projectiles and represent a significant risk for traffic behind.

Falling ice sheets may not always be noticed and drivers may continue to drive with this dangerous roof load.

Precautionary measures:

  • Keep a large distance between you and any truck driving ahead if you notice there is a dangerous load of ice on the roof.
  • Record the truck’s registration number. Inform the police to prevent risks to other drivers from falling ice sheets.
  • You can try, as safely as possible, to make the truck’s driver aware of the dangerous roof load.


All drivers are responsible and must remove snow and ice from their vehicles. Intentionally neglecting this responsibility is punishable by a fine or imprisonment. If an accident occurs causing personal injury and property damage, further severe criminal and civil sanctions can be expected.

The vehicle owner is generally liable for any personal injury and property damage caused due to the operation of their vehicle (Article 58 of the Swiss Road Traffic Act, RTA). Although mandatory liability insurance does cover personal injuries and property damage, insurers are entitled to a right of re¬course in the event of grossly negligent behaviour, which may lead to benefits being reduced or refused.
