 This is KNPR News. I'm Dave Becker. Clark County motorists will see an increase in fuel taxes on Monday with the arrival of July. The Las Vegas Review-Journal reports the taxes will rise by just under 3 cents per gallon of gas sold to 23 cents a gallon. The increase reflects the use of inflation as a way to gauge taxes. The Fuel Revenue Index was approved by Clark County voters in 2014 and extended for 10 years in 2016.
