Rhode Island Has Strict Urban Truck Route Requirements
Rhode Island is the smallest state by area, and its urban areas have strict truck route requirements — commercial vehicles must follow designated routes in Providence and other cities. The state CDL knowledge test covers RI truck route laws, low clearance restrictions on older roads, and specific HazMat rules for densely populated areas.

How much does a California CDL cost?
The government fee for an original Class A or B CDL in California is $100. Skills test retakes are $46 each. These are government fees only — CDL training programs cost significantly more.
What is the minimum age to get a CDL in California?
18 years old for intrastate (within California only) commercial driving. 21 years old for interstate driving, HazMat transport, or carrying passengers across state lines.
Does California accept out-of-state CDL transfers?
Not without retesting. California requires full knowledge and skills retesting for all out-of-state CDL transfers — unlike most other states. If you're moving to California with a CDL from another state, you must complete the full California CDL process.
What is ELDT and does California require it?
ELDT (Entry-Level Driver Training) is a federal requirement for all first-time Class A, B, H, S, and P applicants. California strictly enforces it — you must complete ELDT from an FMCSA-registered training provider before you can apply for a CLP.
