Night driving does require the eyes to work harder because they are constantly adjusting to accommodate the changing light levels.
This is also the case when driving at dawn and dusk.
There is a kind of in-between light condition that occurs in the transition from day to night and vice versa, so be aware of this as it can cause you problems on the road. It will have an effect on your ability to pick up details on the road environment in front of you.
It is easy to fall into the habit of letting your vision drop and lock onto that point where the light from your headlights and the darkness meet, but it’s even more vital that you scan as much as possible at night and try to take in as much as you can.
However, this will only dazzle you and its effects may last a few seconds before your eyes recover. You can travel quite a distance in that time, especially if you are on a highway.
High beam is very beneficial when on the open road but they must be used wisely. Make sure that you dip your high beam as you approach an ongoing car. It is best to this when the oncoming car is a reasonable distance away.
You can also see the glow from the lights increasing as you get close to a crest of a hill.
This is also a good time to dip your lights before the car reaches the crest.
Hopefully, they will do the same.
Sometimes people forget that their high beam is on, this may occur on lonely highways with not a lot of traffic.
So a brief flash of your high beam should alert them to dipping their lights. Just one small piece of advice at this stage, if the oncoming driver doesn’t dip their lights, don’t respond with a blast from your high beam.
I understand that avenging the discomfort this driver has imposed on you may seem like a natural thing to do, but it only makes it worse because you effectively have two oncoming drivers blinded and that isn’t wise. It’s like our parents taught us, “two wrongs don’t make a right”.
If you are dazzled by bright lights you’ll need to slow down and concentrate on looking at the edge of your side of the road.
If someone is closing on you from behind and they haven’t dipped their high beam, you aren’t totally at their mercy.
You can move your internal rear view mirror to the anti-glare position. In fact, a significant number of modern cars have a setting that will automatically do this. You can also move the side mirrors to stop the light aimed directly at your face.
It would also be a good idea to allow this person to pass you at the first opportunity.
Be extra careful when overtaking at night, it can sometimes be difficult to accurately judge distance and that set of oncoming headlights may be closer than you think.
The bottom line with night driving is varying your speed to suit your level of vision. Look as far ahead as you can, increase your braking margins and be even more on guard for the unexpected.
