I‘ve noticed this at all the tollbooths along Interstate 95. This rule doesn‘t make sense to me.
Obviously so water doesn't splash the people at the toll!!!
No, it could break.you do not want that while driving 65 MPH down the freeway!
its a great idea if you dont mind taking the chance of being stranded in the middle of nowhere
As your wiper travels from right to left (towards the A pillar), it gathers water. As the wiper reaches it's furthest point of travel, that water is cast over the outside of the car. If you are approaching a toll booth, that water will hit the toll collector. While it's likely just a few drops, it causes the toll worker to eventually become drenched. So, simply turning your wipers off as you approach helps the toll worker keep dry.
