In тАШNo ParkingтАЩ signs, the oblique red bar is placed at an angle of _________.
60 degrees
45 degrees
15 degrees
30 degrees
45 degrees
In traffic engineering, a 'No Parking' sign is a regulatory sign represented by a blue circular disc with a red border and a single diagonal red bar. The oblique red bar is mandatorily placed at an angle of 45 degrees, slanting from the top left to the bottom right.
IRC: 67-2012 (Code of Practice for Road Signs)
In traffic engineering, a 'No Parking' sign is a regulatory sign represented by a blue circular disc with a red border and a single diagonal red bar. The oblique red bar is mandatorily placed at an angle of 45 degrees, slanting from the top left to the bottom right.
╬╕=45┬░ тАФ standard angle of inclination for the diagonal bar in regulatory prohibition signs
The 45-degree angle is a universal standard design feature used to improve visual recognition from a distance. The diagonal line signifies a prohibition over the symbol contained within the circle (the letter 'P'). This specific geometry ensures that the symbol is distinct from other regulatory signs, such as 'No Stopping', which is represented by two intersecting diagonal bars.
Regulatory signs for prohibition are typically circular in shape.
The diagonal bar indicates the specific prohibition status of the road section.
Proper sign orientation is critical for driver compliance and safety under the Motor Vehicles Act.
Ensures high visibility and rapid comprehension by drivers.
Provides clear distinction from other regulatory sign categories.
Can be obscured by tree branches or poor placement if not installed per IRC standards.
Urban traffic management
Roadway safety infrastructure
Restricted parking zones
The 'No Stopping' or 'No Standing' sign is distinguished from the 'No Parking' sign by having two intersecting bars forming an 'X' at 45 degrees.
Option A, C, and D are incorrect as they do not adhere to the geometric specifications laid out in the IRC guidelines.
B is correct тАФ The standard specification for the diagonal red bar in a 'No Parking' sign is an angle of 45 degrees.
Always distinguish between 'No Parking' (single 45-degree slash) and 'No Stopping/Standing' (two 45-degree slashes forming an 'X') for exams.
