What is classed as speeding in a 30mph zone?
This refers to the lowest level of speeding.
For example, you could be driving at between 21mph and 30mph in a 20mph zone, 31mph to 40mph in a 30mph zone, or 71mph to 90mph on a 70mph road.
At what speed will a 30mph speed camera flash?
If there’s no signs you’re either in a 30mph zone, or it’s national limit. Speedo’s are always 2 – 3 mph over what you are actually doing. Speed cameras give 10% of the speed limit, 33 would be this case. The camera will not flash until you travel at 34 mph in a 30 mph zone.
Are you allowed 10 over the speed limit?
According to guidance from the Association of Chief Police Officers (ACPO) enforcement will normally occur when a driver exceeds the speed limit by a particular margin. And the particular margin is normally 10 per cent over the speed limit plus 2mph.
How fast can you legally go over the speed limit?
In states that use this system for all or some of their roads—California and Texas, for example—it’s legal to drive over the posted limit as long as you are driving safely. For example, if you are driving 50 mph in a 40-mph zone, you are “presumed” to be speeding.
