Today on my usual commute home i came along a country road which i usually come home by.
I was flashed multiple times by multiple cars, i thought they were to let me know about a speeding van or a gaurd with speedometer.
What i drove up to was a full checkpoint. No speed check. The gaurds were obviously on the lookout for someone as they only glanced at my tax and nct etc. I know this as my tax is out and nothing was said.
What i want to know is why, in this day and age (unless for a speed camera) one would flash and warn others about a checkpoint?
Or am i just mad?
