Drivers should allow an extra cushion of space when following:

An SUV.
Drivers whose view to the rear is blocked.
A passenger car.
Explanation

Avoid driving too closely behind large vehicles. The drivers of trucks, tractor-trailers, buses, and vehicles towing campers have limited rear visibility and may not see your vehicle if you are following too closely. Additionally, when you drive directly behind these large vehicles, your view of the road ahead is blocked, making it harder to anticipate traffic conditions. To stay safe, maintain a following distance of at least four seconds to improve visibility and reduce the risk of a rear-end collision.
