A driver is using the stab braking method and the wheels lock up. What should the driver do next?

49 CFR 383.111(a)(14); AAMVA CDL Manual (nhcdm.pdf) Section 2.17.2, p. 2-34

Reapplying the brakes too soon after a stab-braking release, before the wheels are actually rolling again, can keep the vehicle from tracking straight, which is dangerous during a panic stop. Understanding the timing (releasing fully, then waiting for rolling wheels) is what makes the technique work as intended.
