Mobile speed camera detection range

[Speedy Surveyor]

Does anyone know what sort of detection range mobile speed cameras (white vans and laser guns) have?

Depends upon the variant used - some are approved for use at distances up to 999.9m, others less.

Ok, so when my speed detector notifies me of a possible mobile speed trap within 500 yards and I'm travelling significantly over the limit then the chances are I'll be caught (if there is one in place) even if I quickly wipe off my speed?

It takes less than 0.3s to take a measurement - if you are speeding, and if your detector warns you of a laser shot, then chances are you won't have time to react before you are pinged.

My detector uses GPS rather than a laser detector but either way I'm guessing it wouldn't make any difference....

It would if the operator was detecting vehicles travelling from the opposite direction..

Ahhh good point. I suppose with built up areas a 500 yard warning would be good enough regardless of the direction of the laser due to bends in the road, buildings, traffic etc. I guess it's the long straight dual carriageway sections which are the ones I need to be more aware of. Cheers.
