The beam can be aimed in a variety of directions, including towards vehicles moving. However, a laser with a high power can spread its beam so far that it is unable to be seen from the vehicle. In these instances, a higher-powered laser can be employed.<br><br>The laser power of a pointer varies. A laser with a power of 200mW can be seen over a mile away.
