I check my helmet mounted mirror AT LEAST every 15-30 seconds. It's just a quick 1 second glance unless there is potential trouble approaching. Never had a problem since I got my first mirror in 1988. I don't even have to move my head, just my eyes. It's EASY! I do same in my car. I want to know where everybody is located in case something flies off some vehicle in front of me or that vehicle straddles something my car may be too low to clear. I look 15-30 seconds ahead, 1 second behind alternating mirrors in the car - lather, rinse, repeat. All day.
Professionals truck drivers agree.
Federal Motor Carrier Safety Administration (FMCSA) recommendation:
"Tips for Truck and Bus Drivers
Large trucks and buses face unique safety challenges. The following tips can help truck and bus drivers make a plan for road safety. 1. Check Your Blind Spots
Check mirrors every 8-10 seconds to be aware of vehicles entering your blind spots. Additionally, scan ahead on the road about 15 seconds (equating to a quarter mile on interstates, or one to two blocks in cities) for traffic issues, work zones, and other dangers."
