Drunk driving remains a serious hazard on roads everywhere, including in California. While there’s no surefire way to determine if another driver is under the influence, certain behaviors can serve as red flags. Recognizing these signs can help you steer clear of potentially dangerous situations and, if necessary, report the driver to authorities to protect yourself and others.

Erratic Lane Behavior

One of the most common indicators of a drunk driver is difficulty staying in their lane. This can include weaving back and forth, drifting onto the shoulder or into adjacent lanes, or overcorrecting their vehicle. A driver struggling to maintain control of their car is often exhibiting poor coordination or impaired judgment—both hallmarks of intoxication.

If you notice someone swerving unpredictably, maintain a safe distance. Passing such a vehicle or driving too close can put you at unnecessary risk.

Unpredictable Speed Changes

Alcohol impairs a driver’s ability to judge speed and distance accurately. A drunk driver may accelerate suddenly, brake for no apparent reason, or struggle to maintain a consistent speed. These actions can make them unpredictable on the road, increasing the likelihood of an accident.

Keeping your eyes on the road ahead and adjusting your own driving behavior can help you avoid being caught off guard by erratic speed changes.

Ignoring Traffic Signals or Signs

Another warning sign is a blatant disregard for traffic signals and signs. Drivers under the influence may run red lights, stop unnecessarily at green lights, or fail to yield when required. This can create chaos for other drivers and heightens the risk of collisions at intersections.

If you witness such behavior, it’s important to stay alert. Give the impaired driver plenty of space and do not attempt to intervene or communicate with them.

Delayed or Poor Reaction Times

Alcohol slows reaction times and affects decision-making. A drunk driver may hesitate to respond to changing road conditions or obstacles, such as a pedestrian crossing or a vehicle slowing down ahead. They may also react late to turns or forget to use their indicators.

Such delays can result in erratic movements that jeopardize everyone on the road. Staying aware of your surroundings and anticipating the actions of other drivers is key to avoiding trouble.

Driving Without Headlights at Night

Driving without headlights after dark is another potential sign of impairment. Drunk drivers often overlook basic safety practices, such as turning on their headlights when visibility is low. This lack of attention can make their vehicles harder to spot, creating a dangerous situation for everyone nearby.

What to Do If You Encounter a Suspected Drunk Driver

If you believe you’re sharing the road with a drunk driver, the safest action you can take is to keep your distance. Don’t attempt to speed up, pass, or confront the driver. Instead, slow down and allow them to move ahead, putting as much space as possible between their vehicle and yours.

In situations where the driver’s behavior poses an immediate risk to others, pull over to a safe location and call 911. Be prepared to provide details such as the vehicle’s make, model, color, and license plate number, as well as its direction of travel. Your quick response could prevent a potential tragedy.

Staying Safe on the Road

Recognizing the signs of a drunk driver and knowing how to respond can make a significant difference in keeping roads safer. Drunk driving is unpredictable, but your vigilance and responsible behavior can help mitigate its risks.

Regular vehicle maintenance also plays a vital role in road safety. Ensuring that your brakes, tires, and lights are in excellent condition can enhance your ability to react to unexpected situations, including avoiding impaired drivers.
