A vehicle alert system inhibiting a child from being left unattended in a vehicle includes a car seat that is selectively positioned in a vehicle and child is selectively seated in the car seat. A base unit is positioned upon the seat to be sat upon thereby facilitating the base unit to detect weight. The base unit is turned on when the base unit detects weight. A remote unit is carried by the driver of the vehicle. The remote unit is in electrical communication with the base unit. Moreover, the remote unit emits an audible alarm when the remote unit moves beyond a trigger distance from the base unit and the base unit is turned on. In this way the remote unit inhibits the child from being left unattended in the vehicle.
