700.
Ones I got wrong - the train question (did it say the length/weight of the train? Wouldn't that make a difference?), the one about the mile markers increasing/decreasing, and the one about which lane to be in - never knew that the positioning of the exit sign on top of the highway sign represented the exit lane.
I got the stopping distance questions right, but wouldn't it depend on the car's brakes? Damn sure my Golf can stop a lot quicker (servo assisted disc brakes with ABS) than the Beetle (drum brakes all round, no ABS, no power assistance, single leading shoe - LOL!).
