Accidents are dangerous, primarily if the accident occurred very recently. Situations like this are usually unclear, and other drivers must pass the location carefully or offer assistance.

Vehicles that come to a sudden stop may cause an obstacle. Furthermore, the passengers of the broken-down vehicle may leave the vehicle, and cause a hazard to other drivers. Drivers must take special care to avoid passengers who leave a disabled vehicle.

Slippery road conditions are mainly caused by bad weather conditions, but also abnormal liquids (e.g., oil) on the road surface. Such conditions can lead to skidding or unexpected vehicle movements.

Severe weather conditions may reduce the visibility to an extent where drivers must be careful. Drivers should reduce speed and watch out for other vehicles.

Unexpected strong winds (e.g., cross winds) may cause the vehicle to move in unwanted ways. Drivers need to be aware and reduce their speed if needed.

The road’s surface might be damaged, causing the driver to drive slowly and erratically. Examples of such bad conditions are potholes and damaged roads.

Roadworks are construction sites for roadway maintenance. They usually include reduced speed limits and lane changes.

The surface of the road might be damaged causing the driver to reduce speed and drive erratically to avoid road hazards. Examples of such bad conditions are potholes and damaged roads.
