That rather depends on whether it's moving, and how fast.The vehicle will have moved far more than the burst radius of the M30A1.No--weapons have flight times. Even with perfect feeds from unhappy people on the ground you can't drop a GPS guided weapon that takes a few minutes to reach it's target onto a vehicle.
With the M30A1 warhead with its 186,000 tungsten pellets, one does not need pinpoint accuracy against moving vehicles.
Targeting a truck on a road is an easier problem than targeting an aircraft at high altitude, or a merchant ship underway at long range, and the latter problem can be solved by mechanical "computers" of 1940s vintage.
If a rifleman can be trained to 'lead' a target to shoot down aircraft, then I am pretty sure an artilleryman can be similarly trained to hit a moving truck, particularly if said truck is restricted to a prepared road (either due to mud or mines).
Aircraft typically move at pretty steady speeds and the flight time of the shell will be in the 10-20s range. Trucks on roads have quite variable speeds and the flight time of the missiles is a few minutes.
