RCMP in Hampton, N.B., are investigating after a transport truck drove the wrong way on Highway 1 for nine kilometres on Thursday morning.
Police say the truck, owned by RST Transport, left the eastbound lanes near mile marker 154 at about 9:30 a.m., travelled hundreds of metres across the grass median into the westbound lanes and continued into oncoming traffic at full speed until mile marker 163.
No one was injured.
RST spokesperson Mary Keith says the driver "took evasive action when cut off by a passing vehicle."
"The driver endeavoured to pull over, crossed the median and travelled about two kilometres before RCMP safely escorted the truck to the Bloomfield exit," Keith said in an emailed statement.
A witness told CBC News other motorists had tried to alert the truck driver by honking their horns and waving, but he continued on until he was pulled over by an RCMP cruiser with flashing lights.
The truck driver was a 72-year-old man, said RCMP Cpl. Pat Cole.
There is no indication of alcohol or drugs being a factor in the incident, he said.
Police are now investigating the status of the man's operating licence, said Cole.
The transport trailer was empty at the time. It's not yet known what product it had previously been carrying, said Cole.
RST, a member of the J.D. Irving Limited Group of companies, is undertaking its own review of the incident, as per company policy, said Keith.
As part of RST procedures, the driver has been tested, she added.
