Never had this problem here in CA; but first thought is dui. In California cagers call in dui's right away as Cal trans asks for dui enforcement with requesting signs time after time.
Bottom line is if all safe then we have tomorrow.
These roads have hair pin turns most turns are rated 10mph and it's up and down mountains. If he was drunk he would of wrecked. He had a family truck full. So couldn't believe dui.
