In case of emergency
Improving coverage of the cellular network in combination with high maintenance and upkeep costs have resulted in declining usage of emergency telephones for highways. In Belgium and the Netherlands, roadside emergency telephones have been retired from service as of 2017. In case of emergency, drivers are expected to use their own cellphone to alert emergency services. In some sparsely populated areas in Wallonia, roadside emergency telephones are expected to remain operational until 2020.
