Goodbye Gas Tax, Hello Road Charge? 

For more than a century, California, like other states, has used a tax on gasoline to pay for road construction and maintenance. But as revenue from the gas tax declines due to growing fuel efficiency and the increased popularity of hybrids and electric vehicles, the Golden State is exploring the idea of ending the state gas tax and instead charging drivers for the miles they travel. The more distance driven in a car or truck, the higher the tax would be.
