What about safety posters?
I get it. A former student of mine fell out, perfectly sober, hit their head in the worst way and died.
Head trauma killed bank exec in golf cart fall
I heard from the pro I know who works on that course that he was reaching for something on the floor and the driver stopped short for some reason. If I need something on the floor I wait until the cart stops. But really, who would think of that?
I know another golf coach who was the passenger and his leg was dangling and that got cought on a stump, snapped backwards, broke, blacked out and when he woke up he was in the hospital. That was at my HS home course and it didn't make the papers. Keep your feet on the floor.
