30 Essential Road Safety Rules


Every now and then, we come across new vehicles on the road. Hence, it is vital to know and to follow the basic road safety rules and to ensure that everyone else follow these rules too. The road safety rules are designed to suit the best interest of the Indian citizens. In a huge country like India, it may be difficult to execute these safety rules; but, it is not impossible.

Here are 30 essential road safety rules to be followed in India:

1. Keep Left:

Drive adjacent to the left side of the road and let other vehicles in the opposite direction to pass on the right hand side.

2.  Turning Left:

If you want to turn left, stay close to the left side and then, turn left. After turning, continue to stay to the left side of the road.

3.  Turning Right:

When you want to turn right, you should first come to the center of the road carefully and then, turn right keeping your vehicle close to the left side of the road.

4.   Passing:

Always remember to pass or overtake the vehicle in front of yours from its right side.

5.  Passing Prohibited:

Overtaking or passing a vehicle and progress in the same direction is prohibited in the following cases:

If overtaking or passing causes trouble to any other vehicle moving in any direction

Overtaking is prohibited in a curve as you may not have a clear view of the road ahead and sometimes, it may lead to serious accidents

It is not wise to overtake or pass if you see the other vehicle's driver already starting to overtake your vehicle

If the other driver does not give a signal allowing your vehicle to overtake their vehicle

6.  When another Vehicle Overtakes your Vehicle:

You should not try to increase your speed or do anything that prevents the other vehicle from passing or overtaking.

7.  Intersections:

You should be extra cautious while approaching a junction, intersections or a crossing. Make sure that your vehicle does not cause any inconvenience to other vehicles or pedestrians.

8.   Right of Way:

While approaching an intersection, always give a right of way to vehicles already progressing on that particular road. In other cases, you should proceed only after giving way to vehicles approaching from the right side of the road..

9.  Emergency Vehicles:

As a road user, it is your responsibility to give way to fire service vehicles and ambulances.

10.  Pedestrians

Pedestrians have the right of way at pedestrian crossings or zebra crossings.

11.  “U” Turns:

U turns can only be taken when

There is no warning sign nearby

You give a proper indication to other vehicle drivers that you are going to take a U turn either by hand signals or vehicle indicators

You confirm through the mirrors that there is no traffic behind your vehicle

There is no traffic around your vehicle and take U turn only when it is safe

12.  Required Signals:

 If your vehicle indicators get damaged without any warning, what will you do? At this juncture, hand signals can be really helpful and hence, it is essential for you to learn them. Here are certain situations where hand signs can be used when your vehicle indicator or brakes are not in proper working condition:

When your vehicle is slowing down

When your vehicle is preparing to stop

When you are planning to turn right or overtake a vehicle from the right side

When you plan to turn left

When you give permission to the vehicle behind you to overtake your vehicle

13.  Indicators:

By using mechanical devices or electronic devices, you can simplify the signals for indication.

14.  Parking:

When you park the vehicle, make sure that it does not cause any hurdle or disturbance to any other road users.

15.  Registration:

No goods or loads should be kept in a way that hinders the visibility of other vehicles, the headlamps, tail lamps or the vehicle's registration number. If the vehicle's registration number is some way tampered, it should be replaced immediately with a duplicate one.

16.  One way Roads:

In the case of one way roads, try to drive only in the direction indicated on the road signs. Never park your vehicle in reverse on a one way street.

17.  Stop Lines:

When there are stop lines on the road, ensure that you stop the vehicle behind those lines.

18. Towing:

No vehicles should be towed closer to other vehicles on the road. Some of the exceptions are:

Vehicles that are mechanically disabled
x

Partially assembled vehicles

Registered trailers and sidecars

All these vehicles are allowed to tow for the purpose of delivery, reaching the nearest service station, or garage.

19. Noise:

Drivers should not:

Use the horn needlessly

Use the horn in prohibited areas like hospital zones, school zones, etc.

Use horns that are blaring, irritating, or loud

Use vehicles that cause a lot of noise when in motion

Drive vehicles without proper silencers

20.  Traffic Lights and Signs:

Always obey traffic signs, the instructions given by traffic officials or any other authorized person.

21.  Following Distance:

It is better to keep a safe distance from the vehicle in front of you since there is a chance for the vehicle to stop suddenly. When you keep sufficient distance, you will be able to avoid unnecessary hazards.

22.  Right of way on Steep Roads:

When the width of the road decreases, it will be difficult for each vehicle to pass at the same time. In such cases, it is always better to stop your vehicle aside and let the other vehicle pass.

23.  Obstruction of Control:

You should not allow anything that obstructs the view of the road. No one should be permitted to settle, stand, or place anything that hinders his control on the vehicle.

24.  Passing Pedestrians:

Do not drive your vehicle at a speed of more than 25 km/hr, especially when you pass a procession, meeting, strike, or a march.

25. Tractor and Goods Carriages:

It is not allowed to carry passengers on a tractor. Also, drivers of good carriages should not allow more passengers than registered.

26. Loading:

It is dangerous to overload vehicle with materials. There should not be anything in the loads that extend towards the front, back or rear side of the vehicle that cause inconvenience to other road users. Also, it should follow the height restrictions decided by the authorities.

27. Hazardous / Dangerous Materials:

 It is better for a public transport service to not carry explosive, inflammable, or harmful substances as it can be dangerous to them as well as other road users.

28.  Driving in Reverse:

When you take reverse, you should ensure that it does not cause annoyance to any other people on the road.

29. Essential Documents:

A driver should possess the following documents while driving a vehicle: –

Driving license

Registration certificate of the vehicle

Taxation certificate

Insurance certificate

Fitness certificate

Safe Driving Permit

All the above documents should be produced on the demand of a police officer or any authorized person. If the documents are not with them, either the attested copies should be given to the officer directly or sent by post within 15 days.

30.  Additional Regulations:

In addition to the rules mentioned above, the drivers should be aware about their duties, speed limits, weight limits, signals, etc. Also, they should have an idea about the consequences of driving vehicles without relevant documents, drunken driving etc.

The above mentioned rules can be very much valuable for people of all ages. These rules can make the people safe and secure on the roads. Every year, the number of vehicles on road goes on increasing; so does the importance of road safety. Hence, knowing essential road safety rules can help you and your friends from road related crisis.

Job Safety Analysis (JSA) / Job Hazard Analysis

Job Safety Analysis (JSA) is an approach to an accident prevention.

A Job Safety Analysis (JSA) is a procedure which helps integrate accepted safety and health principles and practices into a particular task or job operation. In a JSA, each basic step of the job is to identify potential hazards and to recommend the safest way to do the job. Other terms used to describe this procedure are job hazard analysis (JHA) and job hazard breakdown.

Some individuals prefer to expand the analysis into all aspects of the job, not just safety. This approach is known as total job analysis. Methodology is based on the idea that safety is an integral part of every job and not a separate entity. In this document, only health and safety aspects will be considered.

7 BASIC STEPS OF JOB SAFETY ANALYSIS (JSA):

1.    Job Identification - Communication of Scope

2.    Job Analysis - Identifying The Job Steps

3.    Hazard Identification - Identifying The Hazards In Steps

4.    Hazard Prioritization - Assessing Risk And Priorities

5.    Hazard Controls - Applying Control & Risk

A.    Elimination

B.    Substitution

C.   Engineering Controls

D.   Administrative Controls

E.    Personnel Protective Equipment (PPE)

6.    Documentation - Formalized Method (Communication)

7.    Monitor And Review - Ongoing

3 BASIC STEPS OF SAFETY TASK ASSIGNMENT (STA):

1. Pre Task Planning

2. Hazards Identification & Correction

3. Supervisor And Employee Accountability

HAZCHEM CODE - EMERGENCY ACTION CODE

Emergency Action Code, commonly known as the "Hazchem Code" is a very simple and effective communication device to enable personnel to know at once what precautions or actions are required to deal with emergencies like spills, leaks or fire.

The Hazardous Goods Emergency Action Code (EAC) List is reviewed every two years and is an essential compliance document for all emergency services, local government and for those who may control the planning for, and prevention of, emergencies involving dangerous goods.

The Code:

For Fire-Fighting Response:

1. Jets / Coarse Spray

2. Fog / Fine Spray

3. Foam

4. Dry Agent

Example: A Substance With Hazchem Code 3YE  for PETROL.

The number tells the fire brigade what medium to use to extinguish a fire - in this case 3 indicates that emergency responders should apply foam to extinguish a fire. 

Y indicates appropriate spill response, which in this case is in the 'contain' section of the table. 

This substance must be prevented, by whatever means possible, from entering drains or watercourses. 

When the spill response code relates to the 'Dilute' section of the table, this means that the substance can be flushed away with water.
