State troopers said they issued nearly 1,000 tickets to motorists during a blitz last month intended to bring attention to road worker safety.

Between April 20 and 24, the New York State Police said it conducted 12 enforcement details at a dozen work zones across the state. In some cases, troopers were disguised as highway workers to identify violations.

The state police said it issued 160 tickets for violations of New York’s Move Over Law, which requires drivers to slow down and move over when there is a vehicle parked on the side of the road. This year’s tally is an 84% increase from last year’s blitz.

Speeding tickets made up the bulk of the citations, at 401. Such tickets rose by a third from a year earlier.

According to the state police data, roughly a third of the stops were made along the New York State Thruway.
