How to Stay Safe While Driving in Heavy Rain
Updated: 5 days ago
No. When rain reduces visibility, turn on your low-beam headlights rather than relying on daytime running lights. In Houston traffic, aim to be visible from both directions: front lights don't guarantee your taillights are on.
Check more than the lights at the front
Daytime running lights help other road users notice a vehicle during the day. They are not a substitute for the lighting you need in bad weather. On some vehicles, the daytime setting leaves the rear lights off. A glowing dashboard is not reliable confirmation that the exterior lights are on.
Before your next trip, park safely and learn the lighting controls in your owner’s manual. Find the low-beam setting and the indicators that confirm it. Check the headlights and taillights while the vehicle is secured in a safe place; do not get out to inspect lights beside moving traffic.
Does AUTO take care of rain?
Automatic headlights can respond to the amount of light outside. A rain shower does not always make the sky dark, so do not assume AUTO has selected the lighting you need. Some vehicles also link headlights to the wipers; check your manual for your vehicle’s behavior. If the necessary lights are not on, select the headlights yourself when it is safe to do so.
Use low beams when visibility drops to Stay Safe While Driving in Heavy Rain
The Texas Department of Insurance recommends turning on headlights in rain because other drivers have a harder time seeing your vehicle. The Texas Driver Handbook also specifies low beams for fog, heavy rain, sleet, snow and dust.
High beams are not the fix for a wall of rain or mist. Reflected light can make the view worse. If fog arrives with the rain, the National Weather Service recommends low beams so drivers ahead and behind can see you.
What if the rain becomes too heavy?
Stay Safe While Driving in Heavy Rain. Lights cannot make every storm safe to drive through. Slow down, leave more room and avoid sudden maneuvers. If you cannot see well enough to continue, seek a safe place away from moving traffic, such as a parking area, and wait for conditions to improve. Avoid driving during heavy thunderstorms when possible. Never enter floodwater.
Make a short check before the next storm
Clean the exterior light lenses, check that the lamps work, and replace worn wipers. Learn the controls while parked so you are not searching through menus in heavy rain. The useful habit is simple: confirm that your low beams and rear lights are actually on when conditions call for them.
Check for open safety recalls
A lighting check and a recall lookup serve different purposes. Use your VIN to look for unrepaired safety recalls, then follow the repair or interim instructions for your vehicle. A result showing no open recalls does not replace maintenance or a check of a malfunctioning lamp.
