Big vehicles won't pose great danger in hills. It's because some idiotic car drivers who think they are hero in front of their girlfriends or just to impress them does all blunders and posing as a danger to oncoming vehicles as well as to the bigger vehicles who's a primary victim for braking and stuff.
Once When I was driving uphill from Mudumalai to Ooty in Kalahatti route, a Sunny guy who has sun shades all over his car including driver side downhill coming directly towards me and honking, gawd I just feel to have a monster truck and running over him crushing his head!
That's a rule to give way for uphill vehicles (wrt Ooty-Kalahatti roads) and thanks to the internet for all these junkies taking out their cars and coming out like they know everything in this world.
