UK motorists caught by the A303 Folly Bottom speed camera between May 2003 and August 2004 can apply to get their fine refunded and points removed from their licenses. A court dismissed the case against Claire Allison, 46, who first raised the issue after being cited in the area and noticing there was no speed limit sign.

"I drive a very high mileage and I do my very best to always drive safely," Allison said. "The ticket in the post made me so angry because I knew that I hadn't passed a speed limit sign."

Refunds could cost the government £1 million (US $1.9 million).

Statement of the camera operators and Crown Prosecution Service

In the first six weeks of the enforcement a police statement said more than 5,600 motorists were caught breaking the 40mph limit.
