Why Can’t I Turn On My High Beam At Night?

High beams are one of the nice features of your car. They provide extra light to see better at night and in certain conditions. Most drivers know that switching on your high beams increases your visibility at night.

But have you ever wondered why you can’t turn on your high beam headlights when it’s dark? It is because as a safety precaution, doing that will cause other drivers to lose focus on the road. In the rest of this post, you will find more details about this and answers to other related questions about using high beams at night.


What happens if I turn on my high beam at night?

When you put on your high beam headlights at night, the major thing that happens is that you blind oncoming drivers. What’s wrong with that? You risk having them ram into you (or other objects) as they cannot temporarily see what is ahead of them anymore.

You may not always realize it because you feel the high beam headlight is allowing you to see more than clearly. But that is not the case for the oncoming driver who is much closer than you think.

Blindness for other drivers is a risk of using the high beams when it’s dark outside and you are not driving on a lonely road.

Should you use your high beam when driving at night?

There are a few factors to consider when deciding whether or not to use your high beam headlights while driving at night. High beam headlights should be used due to adverse weather conditions. The purpose of high beams is to allow drivers to see better in foggy or rainy conditions, but they can create a safety hazard if used wrongly.

The best time for high-beam use is during bad weather or when there are no other cars on the road at night. When driving at night, you should only use your high beam if there are no other vehicles in your path.

Is it safe to use my high beams if my headlights are out at night?

It’s important to know when it’s safe to use your high beams. High beam is safe to use when you can’t see enough of the road ahead to drive safely, and they should be turned off when you see other vehicles coming.

It is not safe to have it on where there is oncoming traffic, whether your main headlight is out or not. This is because it increases the amount of glare and brightness coming from your vehicle and that reduces night vision for other drivers.

Is it legal to use a high beam at night?

Each state has its own laws dictating when high beams are allowed. For example, in some states, it is illegal to use high beams if your headlights are out at night, for some, it is allowed only for a certain period.

Some drivers mistakenly believe that they should use their high beams whenever they want because their vehicle has no backup light or because they’re driving in a rural area with few streetlights. However, using your high beam headlights in these situations can actually be dangerous.

At night, your vision is affected and it takes longer for you to react to things happening on the road. That’s why it’s so important to dim your high-beam headlights when approaching another vehicle – so that you don’t blind the driver coming towards you. The distance at which you need to do this varies depending on the state.

Should I use my high beams in foggy conditions?

There are a few things to keep in mind when deciding whether or not to use your high beams in foggy conditions. First and foremost, it’s illegal to use high beams in most provinces while driving in foggy conditions. 

Another thing to consider is the speed of your vehicle. High beam usage should be based on the speed of your car – you don’t need them in a fog if you’re going slower than 70km/h. And finally, remember that using high beams can temporarily blind other drivers.

If all these factors are taken into consideration, then you can make an informed decision about whether or not to turn on your high beams in foggy conditions. Just be sure to watch out for other drivers and be prepared to turn them off when needed.

How to use your high beams properly

The first rule to using your high beam properly is to keep in mind that high beams are not really necessary at night, especially on a busy road. When you always remember this and think of other road users, you are already considering using your high beam the right way.

When to use high beam headlights to stay safe

When turning on your car’s high beams at night, you always want to keep an eye out for oncoming traffic. When you use your high beams too close to another car, it can blind the driver and can cause an accident. Here are a few situations you can comfortably use your high beam:

  1. On long, dark highways, those beams can be a lifesaver.
  2. In foggy, rainy, or snowy conditions, the low beams may improve your visibility instead of the high beams. But the high beam headlights can be used if it is legal to use them at that point in your region.
  3. When driving alone on a lonely road, your high beam headlights can help you in seeing objects in the distance and prepare you for anything on time.

When not to use your high-beam headlights

There are a few instances when you shouldn’t use your high beam headlights while driving. Some of them include:

  1. If there’s a light fog or snow on the ground. When it’s snowy or foggy outside, your car’s lights reflect off the precipitation and make it harder for other drivers to see. It’s important to be aware of this and switch to your low beams whenever visibility is poor.
  2. High beam headlights should not be used to see the road when driving at night where there are oncoming vehicles.
  3. Another time you should not turn on your high beams is when another driver turns theirs on in front of you or even next to you. If they can’t see so well and turn their high beams on, you do not have to do the same as doing that can cause you both to go temporarily blind and might create a dangerous situation for drivers.
  4. You can use your low beams in heavy rain or snow because they consume less power and won’t blind other drivers as much as the high beams.
  5. High beam headlights are more expensive than low-beam headlights because they require more power, so it’s best not to use them unless necessary and in order.

Can you use your high-beam lights if your low beams aren’t working?

If your low beams aren’t working, you can still use your high beam headlights as long as you follow the proper safety guidelines. Make sure to flash or use your high beams within the recommended feet of oncoming traffic.

If oncoming drivers have a high beam and refuse to dim their headlights, keep your eyes on the edge of the road ahead and continue using your normal light to avoid a collision.

When driving, you should never forget that the road is for everyone, not just you. This will help you always do the right thing at all times. You wouldn’t want to be driving at night and have a bright light shine straight into your eyes and cause you to lose focus. That is the same way other drivers would not appreciate that, so keep your high beams for only when you are not putting other drivers at risk.

Always remember, if you turn on your high beams at night, you could possibly end up causing an accident as the glare may be too much on some drivers who may not have a good idea about what to do in such situations.
