You’ll probably hear your driving instructor bang on a lot about checking your blind spot, and he does so for good reason.
Whilst your mirrors are very useful and you should use them, you shouldn’t just rely on them. You need to look at your blind spot too.
We see people fail to check their blind spot a lot when they are changing lanes. When you come to changing lanes, you would have read in your Highway Code about mirror-signal-manoeuvre, which is of course important. But so is checking your blind spot. Make a habit of checking it. This also includes when you are reversing around the corner, bay parking and many other times when you’re on the road.
Be safe. Check your blind spot!
