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