Roadway Marks Used For Speeding Tickets
Look at the two white marks highlighted in the photo below.
Radar is not always the best way to catch speeders, especially in open areas where the police can’t hide.
But, radar isn’t the only option, Police can also use these marks to measure how fast you’re going. This pair of marks will be followed by a second pair further down the highway. In the United States, they’re usually a quarter mile apart and in Canada, 500 meters.
An officer in an airplane or unmarked car will use a stopwatch to time your car between the two pairs of marks. The time it takes will give them your average speed between those two markers, and if it’s high enough then they can write you a ticket. In the case of aerial surveillance, the plane will notify police cars waiting on the ground.
Either way, I’d recommend a good radar detector (where legal of course).
