It seems to as I drive on the Maine Turnpike, I-295, and any highway with an on-ramp in Maine, that drivers do know the proper way to get onto the highway.
The Maine DOT is installing new electronic signs to let drivers know travel times to points on the highway, but it makes me wonder if this is even necessary.
A man trying to escape from police in Portland caused a head on collision and ended up on foot on I-295 grabbing onto cars at full speed trying to get in.
