When are the mandatory turn signal locations in Subject 2?

[Delaney]

There are three instances in Subject 2 where turn signals must be used: exiting a parallel parking space (left turn signal), making a 90-degree turn (left turn signal), and stopping at a designated point on an uphill slope (right turn signal). Penalties for incorrect use of turn signals are as follows: Failure to use or incorrect use of turn signals before starting, turning, changing lanes, overtaking, or parking results in a 10-point deduction. Using the turn signal for less than 3 seconds before starting, turning, changing lanes, overtaking, or parking results in a 10-point deduction. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The test is considered passed under the following conditions: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a garage, parallel parking, stopping and starting on a slope (canceled for C2), 90-degree turns, and driving through curves (commonly known as S-turns) as the five mandatory items (some regions include a sixth item: highway toll card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include pole test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, driving through curves, 90-degree turns, passing through a width-restricted gate, driving over continuous obstacles, driving on bumpy roads, making U-turns on narrow roads, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling.
