Tip of the Month: Sharing the Road: As some of you know, harvest season is in full swing and will continue for the next few months as different crops become ready to be taken from the fields and orchards. What this means is that there are more Semi trucks on the road.  Here are some tips when sharing the road with commercial vehicles.

  • Semi Trucks create wind gusts.  Keep both hands on the wheel when passing a truck or when a truck passes you.
  • Leave plenty of room between you and a truck when stopping on a hill. Trucks may roll back as the driver takes his or her foot off the brake.
  • Don’t speed up when a truck is passing you. Instead, stay to the right and slow down slightly. Let the truck pass you. This will give the truck driver room to pass safely and get you out of the truck’s blind spot faster.
  • If a truck driver is signaling to change lanes, give the driver space. An average truck changing lanes at highway speeds needs an eight-second gap or 700 feet – the length of 2 1/2 football fields.
