What should you do when driving in thick fog?

When driving in thick fog, the best course of action is to pull off the road to a rest area or truck stop. This is primarily due to the significantly reduced visibility that fog creates, which can make it extremely dangerous to continue driving. When visibility is poor, the chances of collisions increase dramatically, as other vehicles may not be visible until it is too late to react.

By safely pulling off the road, you can avoid the risks associated with driving in such conditions. Stopping in a designated area like a rest stop ensures that you are out of the main flow of traffic and can wait for conditions to improve. This approach prioritizes safety for you and other road users.

On the other hand, continuing to drive, even at a reduced speed, does not address the underlying problem of poor visibility. Additionally, paring down to single-lane travel is not a practical solution since it can lead to confusion and potential accidents on the road. Ignoring road signs indicating hazardous conditions is never wise, as these signs are there to warn you about potential dangers.
