One factor is the height of the ramp. The higher the height of the ramp the further the car travels. Another factor is the surface of the ramp.

You can stop a toy car from going down a ramp by placing a barrier at the end of the ramp, such as a wall or a book. Another option is to alter the slope of the ramp to make it less steep so that the car doesn't pick up enough speed to continue rolling. Additionally, you can manually hold the car in place at the top of the ramp.
Before you leave the ramp area
Get in slow lane well before your intended exit ramp comes up, drive with flow of traffic until exit branches off. Then begin to decelerate. (personally I drop a gear and use engine to help slow down) but not to the point of impeding traffic---then simply go on exit ramp and obey signs at end..Stop, Yield, signal light. Then go about your way on surface street
