Tanker surge — half full is the dangerous one

Smooth is fast when the liquid can slap you.

Unbaffled tanks, partial load: the wave hits the front and shoves you. Brake once, wait, don't stab. N endorsement can sit on a CLP. H cannot. We cover it in class and in Student yard. Don't learn surge on I-20.

Can the tanker endorsement go on a Texas CLP?

Yes, N can. Hazmat (H) cannot. We cover surge in class and in Student yard.

Also in Spanish

Cisterna sin baffles, carga a medias: la ola pega adelante y te empuja. Frena una vez, espera, no golpees. El endoso N sí puede ir en el CLP. La H no. Lo vemos en salón y en el Yard de alumnos. No aprendas oleaje en I-20.
