Pat Curran, a traffic officer responsible for the highway stretch from Cape Town to Plettenberg Bay, told the newspaper that criminals were sometimes obstructing the road to get drivers to stop.
“We’re on the lookout on a daily basis, but we don’t know where it will happen next. It becomes a nightmare,” he said.
On Sunday, motorist Trevor Rees was driving with his wife back home to Somerset West when he was forced to stop his car because the highway was littered with several large rocks and pieces of concrete.
“I swerved to avoid the largest piece but hit a smaller piece that caused the front right tyre to burst,” he said.
“I was then approached by two youths armed with screwdrivers who demanded my phone.
“I told them I was talking to the police when one of them attacked me, at which time I gave them the phone.”
Police confirmed a robbery case was being investigated.
