Driving in the USA and Canada
Speed limits outside towns are now almost universally ignored, but most motorists only travel at ten or twenty miles per hour above the limit. These statements should in no way be seen as an encouragement for anyone to break a speed limit; I am merely reporting facts here. If there is other traffic around then the safest procedure is to travel at the same speed as other vehicles.
In towns, speed limits can be as low as 25mph, and are generally obeyed absolutely. It is very rare to see anyone exceeding a speed limit in a town - those that do are almost always stopped by the police.
In many cases there are progressively slower speed limits as you approach a town, followed by progressively higher limits as you leave it.
Speed limits in the USA are specified on road signs in miles per hour, while in Canada they are in kilometres per hour. Speedometers in all modern cars are marked in both units.
