When I am on Summerlin Blvd trying to cross straight over Lower Fayetteville Rd, from both directions, my vehicle will not trigger the traffic light. My small, light-weight truck does sit higher than some vehicles, but it is stock with factory size wheels. A few months ago some change was made to the Summerlin neighborhood exit that allowed my vehicle to successfully trigger the light, but within the last week or two additional work was done (looks like new sensors were put in) and now I'm back to having to wait for another car to trigger the light for me. Note my truck will trigger the light when in the turning lane on the north side of Lower Fayetteville Rd. It only fails in the straights. Thank you.
