A bill for an act relating to driver age qualifications for certain commercial motor vehicle drivers operating solely intrastate to transport hazardous material.

HF 527 would amend Iowa law to require commercial motor vehicle drivers to be at least 21 years old when transporting hazardous materials intrastate in quantities requiring placards. Currently, 18- to 20-year-olds could drive such vehicles for intrastate operations, but this bill removes that exception. It also eliminates a separate exemption allowing 18-year-olds to deliver fertilizers, petroleum, or pesticides within 100 miles of retail stores. The bill would apply standard age requirements (21+) to all intrastate hazardous material transport, aligning with federal standards. Note: The bill was withdrawn on March 12, 2025, and did not become law.
