You must drive to the left.
Probably you know yet but it’s very important to remember that because the first time you will drive on the right you will surely be out of the habit.
Since you drive on the left you must outmatch on the right.
There’s no priority at crossroads. In Europe who has to turn right has the priority but not in Britain; you have also to know that the roundabouts have the opposite clockwise of Europe.
In Britain speed is measured in miles per hour (mph), 1 mph is about 1.6 km/h
So if you find a road sign that says “20” the speed limit is about 30 km/h
A road sign that says “30” the speed limit is about 45 km/h
A road sign that says “40” the speed limit is about 60 km/h
A road sign that says “50” the speed limit is about 80 km/h
A road sign that says “60” the speed limit is about 95 km/h
A road sign that says “70” the speed limit is about 110 km/h
The limits in the roads are:
30 mph for the town and city roads
50 mph for Single Carriageway roads
60 mph for Dual Carriageway roads
And 70 mph for Motorways
