10. Determine is a Dilemma Zone exists for the following situation: An intersection is 90 feet wide. The yellow time is 3.5 seconds, the speed is 40 mph, and the length of a vehicle is 20 feet. Assume a deceleration rate of 10 ft/sec/sec and a perception/reaction time of 1 second. Is there a dilemma zone? If so, how long is it?
