Where are the mandatory turn signal locations in Subject 2?

[LeColin]

There are 3 instances where turn signals must be used in Subject 2: exiting parallel parking (left turn signal), making a 90-degree turn (left turn signal), and stopping at the slope parking point (right turn signal). Penalties for incorrect turn signal usage 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. Turning within less than 3 seconds of activating the turn signal before starting, turning, changing lanes, overtaking, or parking results in a 10-point deduction. Subject 2 has a maximum score of 100 points, with evaluation standards set for disqualification, 20-point deduction, 10-point deduction, and 5-point deduction. The following conditions constitute a passing grade: ① For large passenger vehicles, tractors, city buses, medium passenger vehicles, and large truck license categories, a score of 90 or above is required; ② For other license categories, a score of 80 or above is required. The C1 and C2 license tests include five mandatory items: reverse parking, parallel parking, slope parking and starting (canceled for C2), 90-degree turns, and curve driving (commonly known as S-curves) (some regions include a sixth item: highway toll card collection). The A1, A2, A3, B1, and B2 license tests include pile test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, 90-degree turns, limited-width gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turns, as well as simulated highway driving, continuous sharp mountain turns, tunnels, rain (fog) conditions, slippery roads, and emergency handling.
