Scan the Roadway Ahead to Lookout for Other Vehicles

All drivers must maintain a lookout to see or hear what should be seen or heard.

Heavy commercial vehicles have an extended stopping distance. Most drivers sit high above non-commercial vehicles.

A good commercial driver will look at least 12 to 15 seconds ahead.

At low speeds this is about the length of a city block. At highway speeds the look ahead distance is one-quarter of a mile.
