A special legislative commission has endorsed a plan to raise Maryland’s gas tax another 15 cents. The panel was created by the General Assembly to come up with ways to fund state transportation projects. The Baltimore Sun reports the commission is also in favor of a provision to prevent the extra money from being diverted to other spending purposes. Lawmakers would have to approve any increase in the gas tax or other measures, such as higher vehicle registration fees. If given final approval, Maryland’s gas tax would be among the highest in the country. Car registration and title fees would increase by about 50-percent under the plan, and there would also be increases in bus and rail fees.
