Washington State Patrol Trooper C. Thorson recently published a Twitter post, with a ‘big secret’ to help motorists avoid turn signal tickets.

His secret is simple: Some maximum-strength blinker fluid.

In all seriousness, it’s a great way to bring some humor to a serious problem that causes major confusion and near-wrecks on the roads every day — motorists failing to properly use their signals.
