When experiencing low visibility due to fog, what should you do?

When visibility is low due to fog, the recommended course of action is to reduce speed and stay on the road. This approach ensures that you maintain control of your vehicle while also allowing other drivers to see you, as pulling off the road can be dangerous if visibility is severely compromised. It is essential to slow down because fog can create sudden visibility changes, making it difficult to react to obstacles or other vehicles.

By reducing your speed, you give yourself more time to respond to unexpected situations and help prevent accidents. Using high beams in fog is not advisable because the light can reflect off the moisture in the air, worsening visibility rather than improving it. Maintaining normal speed is also unsafe, as it does not account for the reduced visibility and potential hazards on the road. Thus, taking a cautious approach by slowing down while remaining on the road is the best strategy in such conditions.
