- Select the statements which are true about driving around a large, slow moving vehicle. Rocks or debris can be propelled from the tractor's large tire treads. You can drive close to the tractor since it is traveling under 25 mathrm(mph) . Tractors do not have or create large blind spots. You can pass the tractor on this road if this is a dashed white line. You should pass on the right shoulder to avoid an accident in the left lane if you want to pass. You can pass this tractor on a dashed yellow line if no traffic is approaching from the other direction.
