In most places where I have lived or driven the speed limit sign on the side of the highway is the speed that, if exceeded, will ensure you get a speeding fine. In some places there is a small allowance for error, say 10%, but not always. The net result of this is that most folks drive at the “advertised” limit, or below.
In the UAE its an unwritten rule, or at least it was until today, that whilst the sign may say 120 the cameras are actually set at 140 or even 160 in some places. A pretty big buffer I think.
Going one step further now, according to The National today, the police will now install two sets of signs on major roads AND additional markings on the road itself indicating clearly when this limit or buffer has changed – on the border between Dubai and Abu Dhabi on SZR for example.
“The new information for drivers, along with smart technology, increased patrols and speed limits adjusted for road contexts and conditions, are all intended to combat speeding”
traffic police say
Uh, if I know the actual speed limit is 140 why would I drive 120? Go figure.
