The State of Maryland recently opened its first truck overheight detector system. It's located at a truck weigh and inspection station along Interstate 70, west of Baltimore.

The truck overheight detector system is to assist drivers who often don't know the height of their vehicle loads, according to State Highway Administrator Parker Williams.
Maryland's State Highway Administration and its Port Authority, in a joint effort, plan to install overheight detector systems at the exits of five terminals at the Port of Baltimore.
Consideration is being given to equipping all of the state's truck weigh stations with the systems.
