5 Forward visibility
5.1 General

For the seated driving position the forward visibility requirements of 5.2.1 shall be ensured (see also

Annex A and Annex B).
---------------------- Page: 9 ----------------------
oSIST prEN 16186-5:2019
prEN 16186-5:2019 (E)

The horizontal distance from the driver's eye to the windscreen in seated position shall be a minimum

of 500 mm and an absolute maximum of 1 715 mm. It is recommended to have a maximum of 1

500 mm.

The sightlines as defined in 5.2.1 shall not be infringed by any permanent equipment of the rolling

stock, whether inside or outside the cab.
All visibility criteria shall be applied using both dummies defined in 4.2.
The visibility criteria do not apply to driver instructor locations.
5.2 Forward visibility requirements
5.2.1 Objectives

A good outside field of vision enables the driver to anticipate hazardous situations, taking into account

the exterior environment when the tram vehicle is moving. A good close outside field of vision enables

the driver to manage the restart of the tram vehicle in relation to the exterior environment. The cab

design shall:

— enable all drivers to see the track (free from obstacles, track elements in the correct position);

— enable all drivers t
