Even though the bus is one of the safest vehicles in the world and the risk of accidents when travelling by bus is very low, accidents can still occur. 

Mercedes-Benz has ensured that the consequences of the accident are as limited as possible. Thus, the strength of the bodywork is also an important factor for the high level of passive safety in the Tourismo.

In addition, the Tourismo has partitions, handrails and special seating that absorb energy in the event of a collision or rollover. This means important protection for the occupants of the vehicle. 

Front Collision Guard (FCG) is a unique passive safety system to protect the driver and tour guide in a head-on collision. Front Collision Guard consists of a complex safety system. It starts with a transverse section that forms an underride protection in the event of an accident in the interests of partner protection and can, for example, absorb a car. The structure behind this profile consists of crash elements that specifically dissipate kinetic energy in the event of an impact. 

In addition, the driver's workstation, including steering, pedals and seat, is mounted on a solid frame component that can move completely back in the event of a serious head-on collision and thus increase the survival space by a significant amount of centimetres. Developers not only worked out the effect of the Front Collision Guard mathematically, they also went on to test it in several real-life crash tests. 

The strength of the coach body is also an important factor for the level of passive safety of a coach. With its resistance, the consequences of an accident can be avoided. The high rigidity of the bus body of Mercedes-Benz buses is enhanced by weight-optimised annular frames around the body. The rigidity is defined in accordance with regulation ECE-R 66/02. This defines the precise "survival space" which must be ensured by the design in the event of an accident.
