Advertisement“Our mowing efforts focus on visibility and safety,” said MoDOT State Maintenance Director Darin Hamelink. Crews use a protective “follow” truck to alert motorists they are approaching slow-moving mowers. Drivers are advised to use the following tips to safely pass mowers on rural two-lane roads:Be alert for trucks and tractors with lights flashing and moving slowly, 2-5 mph. Be prepared to stop or drive slowly behind a “follow” truck, especially approaching a hill or curve on a two-lane road. Obey the no-passing zone stripes, and only pass when you can see far enough past the “follow” truck to avoid meeting oncoming traffic.
