Roadvision AI strengthens compliance with IRC 35-2015 through AI road marking inspection, helping authorities maintain hazard road markings and reflective highway markings for safer navigation across India.
Road markings are among the most effective yet understated road safety tools. Under IRC 35-2015, hazard road markings act as visual alerts that help drivers detect dangers early and respond appropriately. When applied correctly, they reduce crash risk without requiring expensive structural interventions.
As traffic volumes grow, proactive monitoring through RoadVision AI becomes essential for maintaining marking visibility and compliance.
IRC 35-2015 – Code of Practice for Road Markings (with Paints) was issued by the Indian Roads Congress to standardise pavement marking practices nationwide.
The code provides:
Hazard road markings specifically identify zones requiring caution and areas where manoeuvres such as overtaking or lane changes may be unsafe.
Consistency in marking design ensures instant driver recognition across different states and road categories.
Hazard road markings serve as preventive visual warnings. They:
These markings function as psychological and visual speed control mechanisms, reducing the likelihood of collisions.
As per IRC 35-2015, hazard road markings are commonly applied near:
Their placement ensures early hazard detection and safer manoeuvring.
Chevron markings consist of diagonal stripes placed between diverging or converging traffic lanes.
They:
Chevron markings are widely used at channelising islands, gore areas, and obstacle approaches.
These stripes are installed upstream of obstructions to gradually redirect traffic.
Typical specifications:
They create a progressive visual narrowing effect that encourages lane discipline.
Obstruction zebra markings are painted directly in front of bridge abutments or fixed structures.
Their purpose is to:
These markings are especially effective in high-speed corridors.
No overtaking zones use solid lines and yellow centre markings where passing is unsafe, such as:
They are critical for preventing head-on collisions in restricted-visibility conditions.
IRC 35-2015 specifies durable materials to ensure longevity and performance:
Application must occur on dry, properly prepared surfaces to ensure adhesion and service life. Under normal traffic conditions, markings typically last 12–18 months before requiring renewal.
When hazard road markings are installed and maintained correctly, they provide:
These benefits significantly enhance reflective highway markings performance across varying traffic conditions.
Despite clear guidelines, several issues affect effectiveness:
Regular inspections and structured repainting programs are essential to sustain marking visibility and performance.
Hazard road markings are a low-cost, high-impact safety intervention. IRC 35-2015 ensures these markings are applied scientifically and uniformly, allowing drivers to anticipate road hazards and navigate safely.
As India’s road network expands, maintaining high-quality reflective highway markings becomes increasingly important for reducing accident risk and improving traffic discipline.
RoadVision AI enhances hazard marking compliance through AI-powered digital monitoring tools such as Pavement Condition Intelligence Agent.
Automated surveys detect:
By enabling real-time inspection and timely repainting, RoadVision AI strengthens safety, accountability, and adherence to IRC 35-2015 nationwide.
Q1. What are hazard road markings under IRC 35-2015?
Hazard road markings are visual warning markings such as chevron markings, obstruction zebra markings, and no overtaking zones used to identify dangerous areas and guide traffic safely.
Q2. Why are reflective highway markings important?
Reflective highway markings improve visibility at night and during rain, ensuring drivers can identify hazards with sufficient reaction time.
Q3. Which materials are recommended for hazard markings?
IRC 35-2015 recommends thermoplastic road paint, cold-applied plastics, and embedded glass beads for durability and retroreflective performance.
