In Lancashire 37 sites have been identified in major roads and areas of concern, including 34 which speed camera vehicles can visit at any time during July, as well as three motorways.
Regular checks are also planned along some of the region's motorways, including the M65, M55, and M6.
A spokesman from Lancashire Road Safety Partnership, said: "Our cameras use highly accurate laser technology to detect speeding motorists but they are also used to identify other offences, including drivers not in proper control or not wearing a seat belt.
"All our mobile sites are risk assessed for safety and we vary how often we attend different locations with sites based on casualty data, known speeding concerns, where a report has been made directly by a member of the public concerned about speeding issues in their area along with any location that has a fixed roadside camera."
