Warnings dependent on location

A method comprising:

• determining a current location of a first alert module which determines a dependency between at least the current location of the first alert module and a current location of a second alert module;
• providing a first warning signal to a first entity based at least in part on the dependency which provides a first condition, wherein the first entity (i) comprises a processor, (ii) is different from the first alert module and the second alert module, and (iii) is independent from the first alert module and the second alert module;
• providing a second warning signal to the first entity based at least in part on the dependency which provides a second condition;
• and
• causing one of the first and second alert modules to send a warning signal in an instance in which another of the first and second alert modules becomes inactive.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions configured to:

• determine a current location of a first alert module which determines a dependency between at least the current location of the first alert module and a current location of a second alert module;
• provide a first warning signal to a first entity based at least in part on the dependency which provides a first condition, wherein the first entity (i) comprises a processor, (ii) is different from the first alert module and the second alert module, and (iii) is independent from the first alert module and the second alert module;
• provide a second warning signal to the first entity based at least in part on the dependency which provides a second condition;
• and
• cause one of the first and second alert modules to send a warning signal in an instance in which another of the first and second alert modules becomes inactive.
