14. Federal Highway 1—Mexico
The only road to link the far-flung towns and villages of Mexico’s sun-baked Baja Peninsula is this narrow, two-lane byway. Shared by freight trucks, oversized RVs and, well, almost every single vehicle on this 1,000-mile-long peninsula, it can get downright hairy, particularly where it twists through the mountains and hugs the coastline between hillsides and sea. Accidents are common and, in many places, guardrails are split open where previous drivers have missed their turns.
In mean places on this highway, it features sheer drops into the sea, winding roads and drivers with dangerous overtaking maneuvers. This wild snake of a highway is an unpredictable nightmare for the many freight trucks, buses, and cars that pass it every day. Watch out for the other drivers – in six (6) Mexican states, you don’t need to pass a test to drive a car. Good luck.
