The Delaware move-over-law is designed to protect emergency personnel and workers. If approaching a stationary emergency vehicle with flashing lights, including tow trucks and public utility vehicles, you must slow down and vacate the lane closest to the stopped vehicle. If changing lanes is unsafe or not possible, you must slow down to a safe and prudent speed for the conditions.

You should always maintain a following distance of at least 3 seconds to the vehicle in front of you according to the "three-second rule" used in Delaware. In bad conditions and at higher speeds, you should consider increasing the following distance to 4-5 seconds so you have time to safely stop if necessary. On slippery roads, it may be necessary to increase the following distance even more.

In Delaware, the standard speed limit in business and residential districts is 25 mph unless signs indicate otherwise.
