Dangers of Driver Fatigue and How to Prevent It

For most people, driving is a part of their daily routine. However, when you get behind the wheel when you are feeling fatigued, it can become a serious safety risk!  Driver fatigue can affect anyone- long-haul drivers, those on cross-country trips, anyone commuting after a late night, or going home after a tiring day. You may not always realize how tired you are until it is too late.  Driver fatigue tends to slow down your reaction time. It can cloud your judgment and make it hard to stay alert. All these conditions can lead to accidents!

How Fatigue Can Impair Driving

When you drive when you are tired, your brain does not function at full capacity. Even if you are really sleeping, you may experience something called microsleep. It is a brief loss of consciousness that lasts for only a few seconds. While that may not seem significant, if you consider highway speeds, these seconds are enough to miss an obstacle, drift into another lane, or fail to brake in time. Fatigue also hinders your ability to process information. You may struggle to read road signs, incorrectly analyze the gaps in traffic, or forget those last few miles you travelled.

In addition, driver fatigue also leads to poor coordination and slower reaction times. This makes it harder to adjust quickly to changes in traffic or unexpected road conditions. When these impairments happen, the results can be quite dangerous- like when someone is driving under the influence. However, unlike alcohol or drugs, fatigue can go unrecognized. This makes it even more sinister! It is not always obvious to others- or even to you- until something goes wrong!

When and Why Fatigue-Related Crashes Happen

Most fatigue-related crashes happen during two time periods- late at night, usually between midnight and 6 am, and mid-afternoon, around 1 to 5 pm. If you notice, these time-frames also match with the natural dips in your body’s circadian rhythm. This is the internal clock that regulates alertness or sleepiness. During these times, your body is inclined to rest, even if you feel like you are fine.

Fatigue-related crashes usually happen on long, monotonous roads like highways. On such routes, the lack of stimulation can lead to drowsiness, or your mind may drift away. These crashes also usually include single vehicles that may veer off the road with no signs of braking or evasive actions. These are clear indicators that the driver may have fallen asleep on the while or was very fatigued. Such patterns can be seen in personal and commercial driving accidents, including many harmful trucking accidents. In such instances, long hours and tight deadlines push the drivers past safe limits.

Recognizing the Warning Signs

Before fatigue leads to a dangerous situation, it tends to give you warning signs! If you catch them early, you can respond before it is too late. Some common signs are repeated yawning, eyelids getting heavy or if you have trouble keeping your eyes open. You may also find that you are drifting out of your lane, missing road signs, or finding it hard to maintain a consistent speed.

Other signs include difficulty remembering the last few miles driven or feeling irritable or restless. If you experience any of these symptoms, it is important that you consider them a driving hazard and treat them as such, too. Not doing so means you are putting yourself and others at risk!

How to Prevent Driver Fatigue

The best thing you can do to prevent driver fatigue is to get enough sleep. For most adults, it is vital to get seven to nine hours of sleep to stay alert during the day. Besides rest, you may also want to plan. For instance, if you are setting out on a long trip, try to schedule breaks every two hours or hundred miles- whichever comes first! Get out of your vehicle, indulge in some stretching, and walk for a few minutes to refresh and reset your focus.

Another good idea is to bring a travel companion if you can. Talking to someone can keep your mind engaged, and you can also switch drivers, when possible, to divide the mental and physical load. You should also ideally avoid driving during the time when you are normally sleeping as your alertness will be naturally lower during this time.

Also, if you begin to feel sleepy on the road, consider pulling over at a safe location for a short nap. Napping for even 15 to 20 minutes can help restore alertness. You can also consider drinking a cup of coffee or another caffeinated beverage before the nap. Caffeine takes roughly half an hour to kick in, so it may help boost your energy.

Conclusion

Driving while fatigued is not just a personal health concern- it can be a serious public safety issue. The risks of drowsy driving are usually underrated, but the consequences can be just as severe as those from other impaired driving behaviors.

That said, it is important to understand how fatigue affects your driving. Try recognizing the early signs and take preventive action so you can stay safe behind the wheel. Make sure to stay alert and know when to take a break. This will help protect yourself and everyone else on the road.
