Rhode Island E-Z Pass is designed to accommodate a variety of vehicles for convenient toll collection. Most passenger vehicles are eligible, including cars and light trucks. Additionally, the E-Z Pass system is equipped to handle larger vehicles, which encompasses standard motorhomes and vehicles towing trailers, provided they do not exceed certain weight restrictions. However, commercial vehicles such as trucks may also use the system, yet they must adhere to specific class designations and requirements that relate to vehicle size and weight. It is important for users to clarify their vehicle type and any associated regulations. For precise information on vehicle eligibility and details regarding specific size and weight limits, it is advisable to consult the official Rhode Island E-Z Pass website.
