A number of reasons. For one, when you exit, you're usually exiting onto a road with a lower speed limit than the one you left. These exits may include a controlled intersection which you're expected to stop at, so you need to be able to stop in a short enough distance that you don't run through the intersection. Additionally, many exits include curves for which it is necessary to reduce your speed in order to maintain control of your vehicle.
slow to a safe speed before the curve
Yes. so don't drive slow, don't speed. :(
Drivers need to be consciously aware of changing speed limits and watch for posted signs in city and suburban driving environments. You would expect: A speed limits of 15 mph B speed limits of 25 mph C speed limits of 35 mph You would not expect to see D speed limits above 45 mph City driving is referred to as "start and stop" driving because traffic is either moving or stopped. Changing speed limits can make traffic slow to a crawl, such as in school zones.
Well, it may make people . . . slow down. Especially if the posted limits are enforced with stiff fines for exceeding them.
I don't think there are limits to how slow an aircraft can fly in any airspace.
The duration of Exit Speed is 1.5 hours.
That depends on the exit, in most cases yes you would slow down when exiting a highway, but there are off-ramps that are mostly straight and lead to another highway.
Exit Speed was created on 2008-12-12.
Parts of the German Autobahn do not have posted speed limits.
speed limits and operation restrictions.
Yes Germany does have speed limits but on a lot of motorways they dont :)
They are not allowed to exceed speed limits
