The correct answer is **No, you cannot overtake on the left side of the road**. Here's why:

- **General overtaking regulations**: On roads, overtaking must be done on the left side of the vehicle you wish to overtake, except in specific situations where overtaking on the right is allowed, such as in the case of trams or when the vehicle to be overtaken clearly indicates a left turn.

- **Specific exceptions**: Although there are situations where overtaking on the right is permitted, such as on urban roads with multiple lanes in the same direction, these do not apply to the question, which refers to overtaking on the left side of the road.

- **Overtaking prohibitions**: Overtaking on the left side of the road is prohibited in situations where safety is compromised, such as on blind curves, hill crests, or adverse weather conditions that impair visibility.

- **Road safety**: Incorrect overtaking can endanger other drivers, cyclists, and pedestrians, especially on two-way roads where the left lane is used by oncoming traffic.

In summary, traffic regulations establish that overtaking must be done on the left side of the vehicle being overtaken, and not on the left side of the road, to ensure the safety of all road users.
