He was responding to reports that the red-shirt movement would parade some 100,000 pick-up and e-tan farm trucks to Bangkok next week.
Suthep said the farm trucks could not run on highways.
He said any vehicle, which block the road, would be towed away and could be damaged during the operation.
He said the protesters should travel by buses and the buses should be parked at Don Muang and the demonstrators should ride free trains to Yoummaroj and walk to Sanam Luang.
