How do the road conditions affect pacing?
Pacing is easiest and most accurate on a straight road, with no hills, dips, or other obstacles and where the officer can see your vehicle continuously as she follows you. This allows her to keep her car at a constant distance behind you while she paces your speed. Hill, freeway interchanges, dips, curves, busy intersections, and heavy traffic make for a poor pacing environment. All of these obstacles can be used to challenge the accurate pacing of your vehicle.
