New Jersey CDL Tanker: Outage Test 2026

Outage is the empty space you deliberately leave in a tank, and the New Jersey N endorsement exam asks about it. This CDL tanker outage test covers why liquids expand as they warm, how much room different products need, and why a tank filled to the very top can be a serious problem by the time it reaches a warm delivery point.

The outage drill also covers the weight limits that stop you from filling a tank to capacity with a dense product, why the amount you can legally haul depends on the liquid as much as the tank, and how outage, surge and load distribution all interact. New Jersey petroleum and chemical haulers deal with these calculations on every load.

New Jersey lists the item total for its tanker endorsement test inside the New Jersey CDL Manual, and that is the only source worth trusting. Use this outage and expansion drill in 2026 until the reasoning behind every partial fill is obvious.
