DRIVEWAY PROFILE (VDOT Standards)
When entering on exiting a driveway from a public street, a sudden change in the driveway
grade will cause an operator of a vehicle to travel at an extremely low speed. For those
entering a driveway, this greatly increases the possibility of a rear end collision. Therefore, to
enhance safety for the traveling public the desirable and maximum grades are pirovided in
Figure 7. If a change in the driveway grade occurs, the profile shall be rounded� by connecting
-the two different grades.
