Position the vehicle in the center of the driving lane between the two lines designating
the lane width. While holding the steering wheel with a controlled grip, allow the
vehicle to find its own direction (simulating hands free). Record the amount of time it
takes for the front right tire to touch the left hand line prior to making a correction to
keep the vehicle in the lane. Repeat the procedure driving in the opposite direction

on the same road). Calculate the average time between the two tests. Is the average
time for the vehicle to lead/drift to the edge of the lane greater or less than 7
seconds?
