Τhe European Transport Safety Council (ETSC) has published the 42nd PIN Flash Report titled How Traffic Law Enforcement Can Contribute to Safer Roads with the active contribution of NTUA. Exceeding speed limits, drink- or distracted- driving, and failure to wear a seatbelt are among the important factors leading to death and serious injury on European roads. Road safety laws have been adopted to guide drivers in their behaviour. Many comply with them willingly. Others, however, would be less likely to comply if it were not for fear of being detected and sanctioned. This is where traffic law enforcement comes in. This Report gives an overview of the current state of road traffic enforcement across the EU, with recommendations for action.
