Without an RV the road is fine. About 12 miles is turn after turn through scenic mountains. Some are 15-20mph turns and the signs saying so are accurate. The highway is a very well traveled popular route with a few scenic vistas along the way. All good road with guardrails.
Stop off in Jerome, walk around the fun shops, wineries and have lunch at Haunted Hamburger or Grapes. Both excellent! Parking in town is often difficult on the weekends if arriving midday. Usually have to park in lot on lowest level of town and use the stair walkways between streets.
