Question: Amy is stopped at a stop light. The driver behind her glances at their phone for just a brief instant, causing them to delay braking. They hit the brakes and slow down considerably but still manage to crash into Amy's car. Her airbag deploys as she is thrown against it. When EMR Khalil gets to the scene and begins to assess Amy, he immediately asks his partner to institute spinal motion restriction. Why do you think Khalil feels that it is necessary to take this precaution?
