When driving in fog, you can see better by using your low-beam headlights rather than high beams. High beams reflect off the fog and reduce visibility. Also, if your vehicle has fog lights, turning them on can help cut through the fog and improve visibility. Avoid using parking lights or switching beams frequently. Keep your windshield wipers and defrosters on to maintain clear windows. Additionally, it is important to slow down, maintain a safe distance from other vehicles, and stay alert.
