Is Drowsy Driving Just As Bad As Drunk Driving?

Drowsy driving is just as hazardous as drunk driving in many respects. Although they stem from different causes—one from lack of sleep and the other from alcohol consumption—their effects on driving performance can be strikingly similar. 

The Impact of Drowsy Driving

Drowsy driving occurs when a driver operates a vehicle while feeling fatigued or sleepy. It impairs attention, slows reaction times, and reduces decision-making abilities, similar to the effects of alcohol. This impairment increases the risk of accidents, particularly during late night and early morning hours when natural sleepiness is highest. Studies have shown that staying awake for 17 hours impairs a driver’s performance to the same level as having a blood alcohol concentration (BAC) of 0.05%, and 24 hours without sleep is comparable to a BAC of 0.10%, which is above the legal limit in Pennsylvania.

According to the National Highway Traffic Safety Administration (NHTSA), drowsy driving is responsible for thousands of accidents each year in the U.S. In 2022, there were 693 fatalities caused by collisions involving drowsy drivers, a 1.1% decrease from 701 in 2021. In 2017, there were an estimated 91,000 crashes, resulting in around 50,000 injuries and nearly 800 deaths. However, the actual numbers are likely higher, as drowsy driving is often underreported.

The Dangers of Drunk Driving

Drunk driving is widely recognized and a more prevalent public safety issue. Alcohol impairs judgment, coordination, and reaction times, all of which are critical for safe driving. The NHTSA reports that approximately 37 people are killed each day in motor vehicle crashes that involve an alcohol-impaired driver.

The effects of alcohol on driving are well-documented: as BAC increases, the driver’s ability to process information, respond to emergencies, and maintain control of the vehicle deteriorates. A BAC of 0.08% (the legal limit in most states) doubles the risk of an accident compared to a sober driver. At higher levels, the risk increases exponentially.

Preventing Drowsy and Drunk Driving

Both drowsy and drunk driving are entirely preventable but require awareness and the following proactive measures:

• Adequate Sleep: Drivers should aim for 7-9 hours of sleep per night and avoid driving when they feel tired.
• Take Breaks: On long trips, take regular breaks to rest and recharge. If you feel sleepy, it’s safer to pull over and rest than to push through.
• Avoid Alcohol Before Driving: Even small amounts can impair your driving abilities. If you plan to drink, arrange for alternative transportation.
• Know the Signs: Warning signs of drowsy driving include frequent yawning, drifting out of your lane, and difficulty keeping your eyes open. 

How To Spot a Drowsy or Drunk Driver

Spotting a drowsy or drunk driver is crucial for staying safe. Both types of impaired drivers exhibit similar signs that can help you identify them:

Weaving or Drifting

A common sign is a vehicle that weaves between lanes or drifts off the road and then suddenly corrects. This erratic movement indicates that the driver may be struggling to stay focused or awake​.

Inconsistent Speeds

Drowsy or drunk drivers often have difficulty maintaining a consistent speed. They might accelerate or decelerate without reason, driving too fast or too slow compared to the flow of traffic​.

Delayed Responses

These drivers may be slow to respond to traffic signals, such as hesitating at green lights or taking longer than usual to brake when necessary​.

Frequent Braking

Constant or unnecessary braking can indicate that the driver is overly cautious, confused, or reacting slowly to changes in the road environment​.

Poor Judgments

Impaired drivers often misjudge distances or turns, leading them to make wide, abrupt, or unsafe turns. They may also struggle with keeping a safe distance from other vehicles​.

Headlights Off at Night

Drunk or drowsy drivers may forget to turn on their headlights at night, which is a serious safety hazard.

If you notice a driver exhibiting these behaviors, maintain a safe distance and consider reporting the vehicle to local authorities. Avoid attempting to pass or confront the driver, which could lead to dangerous situations. If you are involved in an accident, making sure you contact a top-rated Philadelphia car accident attorney as soon as possible is very essential.
