The effect of grade on safe overtaking sight distance is_______________?
  • (A)  to increase it on descending grades and to decrease it on ascending grades
  • (B)  to decrease it on descending grades and to increase it on ascending grades
  • (C)  to increase it on both descending and ascending grades
  • (D)  to decrease it on both descending and ascending grades
If b is the wheel track of a vehicle and h is the height of centre of gravity above road surface, then to avoid overturning and lateral skidding on a horizontal curve, the centrifugal ratio should always be________________?
  • (A)  less than b/2h and greater than co-efficient of lateral friction
  • (B)  less than b/2h and also less than co-efficient of lateral friction
  • (C)  greater than b/2h and less than co-efficient of lateral friction
  • (D)  greater than b/2h and also greater than coefficient of lateral friction
