Making a 'U' turn can be dangerous and unlawful under these specific conditions due to the increased risks posed to both the driver and other road users.

When making a 'U' turn on a curve or on a hill where the view is obstructed, it can lead to serious accidents since other vehicles may not have enough time to react if they cannot see the turning vehicle. This rule is in place to enhance visibility and ensure safety when navigating potentially hazardous road conditions.

Similarly, turning on or near a railway crossing poses a significant risk, as it can obstruct the tracks and create dangerous situations where a vehicle may be caught on the tracks, leading to potentially tragic outcomes. The law specifically restricts such maneuvers within 30 meters of a railway crossing to prevent accidents.

Additionally, making a 'U' turn within 150 meters of a bridge, viaduct, or tunnel is also prohibited if the driver's view is obstructed. This limitation is crucial because these structures can create blind spots where the visibility of oncoming traffic is compromised.

These conditions highlight the importance of maintaining safety distances and visibility when driving, which is essential for preventing collisions and ensuring the safety of all road users. Therefore, recognizing all of these scenarios collectively emphasizes the comprehensive
