State Police yesterday were continuing their search for the driver who ran over a veteran trooper searching for speeders in a South Boston tunnel.

Trooper Joseph Drane, 55, of Stoneham, suffered a broken leg and some arm and facial injuries as a result of the crash, police said.

The 24-year veteran was inside the tunnel under Frontage Road leading to South Boston and I-90 when he was hit by a dark sedan about 9 a.m.

When other troopers arrived on scene, Drane was conscious and talking to them, authorities said. He was taken to Boston Medical Center and his wife and one of his two older children were with him.

There were multiple surveillance cameras in the area where the trooper was hit and police were reviewing that footage. Physical evidence was also left at the scene, police said.

The carry-over of last year’s rash of struck troopers has caused continued frustration for State Police officials.

“It’s more than frustrating,” said State Police Colonel Marian McGovern. “It keeps happening. We keep saying: ‘What more can we do?’”

McGovern said officials are working with MIT and UMass to study technology and driving ability and training to lessen the number of injured troopers.
