Longitudinal road markings are used to regulate and guide traffic flow on a carriageway. Double solid longitudinal lines indicate a strict restriction on lane changing or overtaking, broken lines allow for controlled lane changes, and solid lines act as guiding lines where lane discipline is required.
IRC:35-2015 (Code of Practice for Road Markings)
Longitudinal road markings are used to regulate and guide traffic flow on a carriageway. Double solid longitudinal lines indicate a strict restriction on lane changing or overtaking, broken lines allow for controlled lane changes, and solid lines act as guiding lines where lane discipline is required.
Road markings are designed based on traffic safety standards to ensure lane discipline. Double solid lines signify maximum restriction (no overtaking), broken lines serve as indicators for traffic lanes or dividing lanes for overtaking, and single solid lines often act as guiding or boundary lines to maintain safety at specific sections.
Double solid lines are prohibited for crossing except during emergencies.
Broken lines are used to separate lanes where overtaking is permitted.
Solid lines are used to guide traffic or demarcate edges/lanes where caution is required.
Ensures systematic traffic flow
Reduces potential for head-on collisions
Can be obscured by snow, heavy rain, or wear and tear
Requires regular maintenance to maintain visibility
Divided highways
Urban arterial roads
Approaches to junctions or bridges
A-4: Double solid lines represent the most restrictive condition.
B-3: Broken longitudinal lines indicate lanes on multi-lane roads.
C-1: Solid lines are often used to define lanes or as guiding lines for traffic.
D is correct тАФ Double solid lines (A-4) signify maximum restriction, broken lines (B-3) indicate lane markings, and solid lines (C-1) act as guiding or regulating lines.
For competitive exams like SSC-JE, always refer to the IRC guidelines (e.g., IRC:35) for traffic signs and markings as they are the standard reference for Indian road engineering.
