The Federal Motor Carrier Safety Administration (FMCSA) requires that you hold a CLP (Commercial Learner’s Permit) for at least 14 days before you can schedule and take your CDL skills tests. During this time, you must complete Entry-Level Driver Training (ELDT) from a provider listed in the Training Provider Registry (TPR). Because commercial driving involves great high responsibility, this training is crucial for building safe -driving habits. It will prepare you for real-world situations and challenges you will often encounter on Washington’s roads.
When you’re behind the wheel of a tanker, there’s no room for error. Even a small mistake can be disastrous, especially when if you’re hauling hazardous liquids or gases. The official Commercial Driver Guide (Washington CDL Handbook 2026) discusses commercial driving theory and its various aspects. You will learn tanker vehicle safety practices, pre-trip inspections, and emergency procedures. We recommend reading this manual multiple times during your learning phase. When you’re ready, you can use our practice tests to evaluate your knowledge.
