If you crash while driving in fog, what should you do?

When faced with a crash in foggy conditions, getting the vehicle off the road if possible is the safest course of action. This is important because staying on the road can put both the occupants of the vehicle and other drivers at risk, especially in low visibility situations. By moving the vehicle to a safer location, you reduce the chance of a secondary collision and allow for emergency responders to have clearer access.

It's also critical to be cautious during this process, as you need to be aware of your surroundings and other vehicles, which may be difficult to see in the fog. Once your vehicle is safely off the road, you can then assess the situation more clearly and can either wait for assistance or call for help.

The other responses do not adequately address safety in an accident scenario. For instance, staying in the vehicle may expose you to further danger, especially if other vehicles cannot see you. Turning off all lights might prevent you from being seen by other drivers, which increases risk. Driving to a service station can also be hazardous, as it may mean navigating more through poor visibility instead of addressing the situation at hand.
