Should You Drive Slower At Night?

Should You Drive Slower At Night?

When the sun sets, and darkness descends, the rules of the road can change. Curious about whether you should adjust your driving speed when nightfall arrives?

Driving slower at night is generally recommended due to reduced visibility, increased risk of encountering unexpected hazards, and the potential effects of fatigue on driver alertness. By adapting your speed to the conditions and being extra cautious, you can enhance safety, react promptly to unforeseen circumstances, and ensure a smoother and more relaxed driving experience after dark.

In this article, we explore the reasons behind driving slower at night, examining key factors that affect safety and offering practical insights to ensure your nighttime journeys are secure and worry-free.

Reasons to Slow Down at Night

1. Slower Reaction Times

Driving at night can cause you to have slower reaction times.

This means you won’t be able to react to hazards, other vehicles, or traffic signs as quickly as you would in the daytime.

The reason for this is the darkness affects your physical circadian rhythm and makes you relax or groggy. 

If you are driving down the road at night, feeling slightly relaxed or groggy, you may not have an appropriate reaction time if a vehicle pulls out in front of you from a side road or if an animal darts into the road from the trees.

Reasons to Slow Down at Night

2. Animals on the Road

Animals on the road can be a very common hazard in many rural and country areas. During the early evening, deer, elk, and moose are a common sight along some roads or crossing the roads. 

Later in the night, raccoons, opossums, foxes, and other small animals can be common, including in heavily populated areas of the city.

These animals may be in the grass along the side of the road, and dart into the road as your vehicle gets closer leaving you to react in a very short amount of time.

3. Shorter View Distance

When compared to daytime driving, driving in the dark reduces your view distance by a considerable amount – even if you have properly installed headlights.

Whether you are driving in the day or the night, scanning the road well ahead of your current position is good advice.

It can be even more important when driving at night due to the reduced visibility overall.

Headlights are designed to light up the road ahead of you, but when using low beams you may only be able to see up to 250 feet in front of you.

With high beams, or brights, your view distance may be twice that at around 500 feet. This is still considerably less than you would have in the sunlight of the day.

4. Cold Weather Hazards

The temperatures normally drop during the night, and in the winter, late fall, or early spring months this can create additional hazards on the road.

Rain itself can be a driving hazard in the darkness since it reduces visibility even more, but even after the rain, you should be very aware of potential cold weather hazards.

When crossing bridges, water on the road can become thin but very slick and almost invisible ice. This can send your car into a spin or rapidly reduce traction leading you to overcorrect or slam on the brakes.

When crossing bridges at night in cooler weather, especially after rain, it’s important to slow down and be prepared for a loss of traction.

4 Tips for Safe Night Driving

1. Drive Defensively

Driving defensively is something you should always do, no matter the time of day or how long the trip is.

Driving defensively means you are watching other drivers’ actions just as much as you are watching your own road in order to ensure they are not drifting into your lane or attempting to make a turn that can be dangerous for you.

2. Stay Alert

Staying alert is extremely important whether you are driving in the daytime or at night. It’s not uncommon for drivers to become drowsy or lose focus when driving at night. If this happens to you, don’t be afraid to pull over when necessary.

Pulling over at a wide area in the road, a gas station, a restaurant, or other public place can give you a chance to step out of the vehicle, stretch your legs, and get your blood pumping. This helps increase your alertness and makes the rest of your drive home safer.

In extreme cases, it is not against the law to pull over at a rest stop or interstate on or off ramp in order to get a few hours of sleep.

In fact, many highway patrol officers will recommend you get some sleep instead of trying to finish your night-time trip while being drowsy or sleepy.

3. Dim your Dash Lights

Darh lights, such as your speedometer, gas gauges, and other signals, can be extremely bright in the dark interior of your vehicle. This is especially true in modern vehicles that use LED lights on the dash.

Almost all vehicles have some way to adjust the brightness of your dashboard electronics. Adjust these lights so they are still visible, but considerably more dim than they would be during the daytime.

Bright lights on your dash and your interior overhead dome light can be very distracting. They can also cause reflections on windows or glasses you may be wearing.

As long as you are still able to view your dash lights to keep an eye on your speed, oil pressure, and other necessary notifications, it’s bright enough.

4. Look Far Ahead

Even though visibility at night will be reduced, be sure you actively search the road well ahead of your current location.

Look for possible reflections of animal eyes, vehicles on side streets, or other hazards that may cause problems.

If you notice any of these, it gives you plenty of time to react and avoid them. In addition to checking the road well ahead of your position, it’s also important to check your mirrors every few seconds.

This gives you a quick view of vehicles in your potential blind spots.

Is Driving at Night Safe?

According to the National Highway Traffic Safety Administration or NHTSA, driving at night is three times more likely to result in severe and potentially fatal accidents.

However, taking the proper precautions covered above can help keep you safe at night.

If you are not comfortable with driving at night, don’t!

There are many people that prefer not to drive at night, or who are physically unable to drive at night due to anxiety, night blindness, or other issues with their vision and reaction time.
