My husband was riding a motorcycle with his friend and they both got exact same speeding ticket, 30 over the speed limit. They were riding in a same lane but not side by side (they were going 90 so riding side by side is not safe). When my husband asked cop which bike did he clocked, cop told him that they were riding side by side, and that’s why they’re getting the same ticket. Oh, and cop gave them that excuse that he pulled them over and giving them a ticket for safety. That’s bunch of bull. Can radar gun clock two motorcycles at the same time? BTW, we live in TX.
BTW, they were by themselves on the road, so no danger to anyone else. My husband owns a radar gun, and we know that it will clock only fastest or the biggest object headed toward you. They are not unsafe riders. Proud to say no accidents, except for colliding with bugs :D
It doesn’t really matter.

They don’t need radar to prove you were speeding.

The cop clocked one. Used that one as reference for the other.

His testimony is all that’s needed "they were going the same speed." That’s evidence enough. Doesn’t matter "side by side".

Your husband can commit perjury and tell the judge he wasn’t going the same speed, that he was going 30mph slower than the other guy. (I know it’ll be perjury based on your question).

It’ll be your husband’s word against the police officers.

good luck.
