2 cards from this section. Quick, good the night before a test.
What is overtaking sight distance?
Think about what a driver needs to see and do.
Name one factor that affects overtaking sight distance.
Consider what impacts how quickly a driver can respond.
What is OSD important for?
Think about how it relates to road safety.
True or False: A steeper road gradient always aids acceleration during overtaking.
Consider what happens to vehicles going uphill versus downhill.
A vehicle traveling at 90 km/h needs to overtake a slower vehicle moving at 60 km/h. The driver has a reaction time of 2.5 seconds, and the road is flat. Calculate the OSD considering all factors.
Start by calculating each part of the equation separately.
Analyze how a steep uphill gradient would affect the OSD if the speed limit is 80 km/h, and vehicles must accelerate to safely overtake.
Consider how gravity influences vehicle acceleration.
