Secondary contacts occur when a vehicle disengages from primary contact, rotates, and strikes the opposing vehicle a second time.

Secondary contacts occur when a vehicle disengages from primary contact, rotates, and strikes the opposing vehicle a second time.

• A. The first contact between vehicles
• B. A vehicle disengages from primary contact, rotates, and strikes the opposing vehicle a second time
• C. A vehicle stops immediately after impact
• D. A vehicle hits the road shoulder

Answer: (B)

Secondary contact is a second impact that happens after the first collision has already occurred and the vehicles have separated. In a crash sequence, one vehicle may disengage from the initial contact, rotate or change direction, and then come back to strike the other vehicle again. The description precisely captures that sequence: disengaging from primary contact, rotating, and hitting the opposing vehicle a second time. The other options describe the first contact, stopping after impact, or leaving the roadway, which do not reflect a second impact between the vehicles.
