Driver Courtesy When Driving in the Rain
Driver courtesy in the rain goes beyond basic legal requirements—it is about respecting other road users, reducing hidden hazards like road spray, and preventing accidents on slick pavement.
Essential Rules of Rain Courtesy
• Turn on your headlights: In places like California, turning on your headlights whenever your windshield wipers are active is a legal requirement, not just a courtesy. It ensures drivers behind you can see your taillights through dense spray.
• Watch your splash around pedestrians: Slow down when approaching bus stops, crosswalks, or pedestrians walking on sidewalks. Blasting through a roadside puddle at normal speed splashes dirty water onto people waiting or walking nearby.
• Avoid tailgating large trucks and buses: Commercial trucks throw up massive sheets of water from their large tires, which completely blinds the driver behind them. Back off to a much larger following distance (at least 6 to 7 seconds) or carefully pass when it is safe.
• Match your lane and speed to the flow: Drive in the middle lanes, when possible as water tends to pool and collect in the outer lanes due to road crowning. If you need to drive significantly slower than the speed limit, keep to the right lane so faster traffic can pass safely without frustration.
• Signal and brake early: Wet pavement drastically increases stopping distances. Easing off the gas pedal early and tapping your brakes gently alerts the driver behind you well in advance, preventing rear-end collisions caused by surprise braking.
• Turn off high beams: High-beam headlights reflect off falling raindrops and wet asphalt, creating a blinding glare that hurts the vision of oncoming drivers. Stick to low beams.
Manage Spray Around Large Vehicles
• Give trucks and buses space: Do not follow large trucks or buses too closely. Their massive tires kick up heavy road spray that blinds your windshield and reduces visibility.
• Pass with care: If you must pass a semi-truck or bus on the highway, do it quickly and safely without lingering in their blind spots or spray zone.
