The shelf registration statement, when declared effective by the Securities
and Exchange Commission, will allow Image Sensing Systems the flexibility to
offer and sell from time to time in the future, in one or more public
offerings, up to approximately $15 million of common stock. The specifics of
any future offering, along with the prices, terms and the use of proceeds of
any such securities offered, will be determined at the time of any such
offering, and will be described in detail in a prospectus supplement filed at
the time of any such offering.

Ken Aubrey, President and CEO, said, "This filing is intended to give us
flexibility in the capital raising process and provide us the opportunity to
move quickly into the capital markets now and in the intermediate term in
support of our stated acquisition strategy."

The shelf registration statement has been filed with the Securities and
Exchange Commission but has not yet become effective. The securities
registered may not be sold, nor may offers to buy be accepted, prior to the
time the registration statement becomes effective. Image Sensing Systems has
no current commitments to raise capital under this shelf registration
statement.

This press release does not constitute an offer to sell or the solicitation of
an offer to buy any securities, nor will there be any sale of the securities
in any state or jurisdiction in which such offer, solicitation or sale would
be unlawful prior to the registration or qualification under securities laws
of any such state or jurisdiction. An offering of the securities covered by
the registration statement will only be by means of a written prospectus
supplement.
