Intersection

intuition

Our roads are full of intersections – T-junctions, crossroads, roundabouts, dog legs… you name it. See if you know the rules to safely negotiate these real-life SA intersections.

Words: Andrew Rasch

1. The blue car is turning left onto Osmond Terrace but there's a red left-turn arrow shown. There's space in the left lane to pull up next to the red car, but the blue car would be stopped in a bike lane. Which of the following statements is most accurate?

A. The blue car can't stop to turn left, because it'd be blocking a bike lane
B. The blue car can stop to turn left, but only outside of peak times

B. Yellow car, blue car, red car
C. Red car, blue car, yellow car
D. Yellow car, red car, blue car

7. The blue car on Tapleys Hill Road near Harbour Town is stopped in the left lane at the intersection with West Beach Road, where three lanes become two up ahead. There's also a red car in the middle lane. Once the lights turn green, what is the safest way for the blue car to complete a zip merge?

A. Minimise potential collisions by flooring it to get to the merge point first
B. Accelerate slowly, then stop to give way to all cars in the middle lane
C. Accelerate in an appropriate manner, giving way to the red car if it's in front at the merge point

8. The red car is turning left into the left lane on Bookpurnong Terrace in Loxton. At the same time, a blue car is exiting the roundabout onto Bookpurnong Terrace. Which of the following is most accurate?
