How many intersection questions can I get wrong?

Zero. Intersections is a must-pass category — one wrong answer of the five fails the mock exam regardless of your total score.

Who goes first at an unsigned intersection?

Give way to the vehicle on your right by default; if turning right, also give way to oncoming straight/left-turning traffic and pedestrians.

ACT Intersection Rules Explained

Intersections is one of the four must-pass categories in the ACT knowledge test: a single wrong answer here fails the whole mock exam. Most questions test who gives way to whom, so the priority rules are the key to scoring.

Three types of intersection

T-junction: one road ends at another; the terminating road gives way to the continuing road.
Cross roads: two continuing roads meet.
Roundabout: entering vehicles give way to vehicles already on the roundabout.

Unsigned, unsignalised intersections

With no lights and no Stop/Give Way sign, when going straight you give way to traffic on your right — the most-tested default rule.

Going straight: give way to vehicles on your right.
Turning left: give way to vehicles on your right and pedestrians crossing the road you enter.
Turning right: give way to vehicles on your right, oncoming traffic going straight or turning left, and pedestrians.

Stop and Give Way signs

A STOP sign means a full stop before proceeding; a GIVE WAY sign means you may roll on but must give way to traffic on both sides and to crossing pedestrians. Both put you on the giving-way side.

Reading diagram questions

Check for signs/lights first — the car with the Stop/Give Way sign gives way.
No signs? Identify the intersection type (T-junction vs cross road).
Check the turn — right turns usually give way to the most traffic.
If unsure, the handbook rule is: give way to all other vehicles.
