The History of Road Safety: Key Milestones

Evolution of Mobility: Milestones in Road Safety

From the first horse-drawn carriages to the era of autonomous driving, the journey toward safer roads has been defined by groundbreaking innovations, visionary engineering, and life-saving legislation.

For nearly a century, DEKRA has been at the forefront of this evolution. To provide you with a clearer perspective on how far we have come, we have organized the most pivotal moments in transport history into key thematic areas. Explore the milestones that have shaped our modern world, organized into the areas of technology, infrastructure, and the legal frameworks that keep us safe every day.

    1865: First braking systems

    The introduction of solid rubber tires and mechanical spoon brakes marked the earliest necessity for dedicated deceleration technology in personal mobility.

    1885: The Birth of the Motorcycle

    Gottlieb Daimler presented the "Riding Carriage" (Reitwagen), recognized as the world's first motorcycle powered by an internal combustion engine.

    1886: The First Automobile

    Carl Benz filed the patent for the "Benz Patent-Motorwagen Number 1," effectively ushering in the era of the modern automobile.

    1888: Re-invention of Pneumatic Tires

    J.B. Dunlop successfully re-invented and implemented pneumatic tires, significantly improving vehicle stability and road contact.

    1902: Disc Brake and Speedometer

    Frederick W. Lanchester patented the disc brake, while Otto Schulze developed the eddy-current speedometer, two critical tools for vehicle control.

    1921: Hydraulic Braking System

    The Duesenberg Model A became the first production vehicle equipped with a hydraulic braking system for more consistent and powerful stopping.

    1923: Compressed-Air Brakes

    The introduction of four-wheel compressed-air brakes by Knorr marked a major safety milestone for heavy commercial vehicles.

    1946: Patenting of Radial Tires

    Michelin patented the radial tire, which offered superior durability, grip, and safety compared to traditional bias-ply designs.

    1951: Invention of the Crumple Zone

    Béla Barényi patented the concept of a rigid passenger cell with front and rear shock-absorbing zones, the foundation of modern passive safety.

    1951: Early Airbag Patent

    Walter Linderer filed an early patent for an inflatable "airbag" designed to protect vehicle occupants during a collision.

    1959: Three-Point Safety Belt

    Volvo engineer Nils Ivar Bolin patented the three-point safety belt, which remains the most significant life-saving innovation in automotive history.

    1963: Safety Steering Column

    Béla Barényi patented the "safety steering shaft," designed to prevent the steering column from entering the cabin during a head-on impact.

    1963: Launch of Child Safety Seats

    The "Niki" model by Storchenmühle was launched as the world's first dedicated child car seat for young passenger protection.

    1971: Patent for the Driver’s Airbag

    Daimler-Benz AG filed a patent for a functional, production-ready driver’s airbag, moving the technology toward standardized automotive use.

    1981: Market Launch of the Driver Airbag

    Mercedes-Benz introduced the driver airbag and belt tensioner as a standard safety feature in the S-Class, marking its commercial breakthrough.

    1993: First use of the pedelec principle

    Yamaha introduced the Power Assist System, establishing the principle where an electric motor provides assistance only during active pedaling.

    2003: Introduction of radar-based Collision Mitigation Brake System

    Honda launched the world’s first radar-based autonomous emergency braking system in the Inspire, using sensors to predict and mitigate the severity of rear-end collisions.

    2006: First Emergency Braking Assist in heavy trucks

    Mercedes-Benz introduced the "Active Brake Assist" in the Actros, marking a breakthrough in heavy vehicle safety by automatically initiating emergency braking to prevent accidents.

    2012: First Pedestrian Airbag

    Volvo introduced the first-ever pedestrian airbag in the V40, aiming to mitigate injury risks for vulnerable road users outside the vehicle.
