Safety Regulations, Equipment, and Emergencies

A common law in many states is 'wipers on, lights on'—if you need your windshield wipers, you are also legally required to turn on your headlights.

To properly document a car accident scene for insurance purposes, you should photograph not just the vehicle damage, but also the wider context, including skid marks, road debris, and any relevant traffic signs.

To avoid confusing other drivers, if you plan to turn at an intersection that is immediately after another, you should wait until you are passing through the first intersection before activating your signal.

Using your car's 'recirculate air' button traps moisture inside the cabin and will cause your windows to fog up much faster.
