Where does a no-parking zone start when there is a no parking sign?
<p>In the United States, Where does a no-parking zone start when there is a no parking sign? Assume the sign is the first such sign on this stretch of road.</p>
<p>Can I park immediately at (before) the sign?  Or does the zone extend back before the sign, perhaps to some range from where it can be seen?</p>
<p>For example, is this car parked legally, assuming the nose of the car is not past the sign?

<p>This &quot;No Parking&quot; sign is the sign the Manual on Uniform Traffic Control Devices (MUTCD) has designated R8-3. According to the MUTCD, to which all states are required to adhere, <a href="https://mutcd.fhwa.dot.gov/htm/2009r1r2/part2/part2b.htm#section2B46" rel="nofollow noreferrer">section 2B.47</a> paragraph 18, this sign would indicate that <em><strong>any</strong></em> parking is prohibited along a given highway:</p>
<blockquote>
<p>In rural areas (see Figure 2B-25), the legends NO PARKING ON PAVEMENT (R8-1) or NO STOPPING ON PAVEMENT (R8-5) are generally suitable and may be used. If a roadway has paved shoulders, the NO PARKING EXCEPT ON SHOULDER sign (R8-2) or the NO STOPPING EXCEPT ON SHOULDER sign (R8-6) may be used as these signs would be less likely to cause confusion. <strong>The R8-3 symbol sign or the word message NO PARKING (R8-3a) sign may be used to prohibit any parking along a given highway.</strong> Word message supplemental plaques may be mounted below the R8-3 or R8-3a sign. These word message supplemental plaques may include legends such as EXCEPT SUNDAYS &amp; HOLIDAYS (R8-3bP), ON PAVEMENT (R8-3cP), ON BRIDGE (R8-3dP), ON TRACKS (R8-3eP), EXCEPT ON SHOULDERS (R8-3fP), LOADING ZONE (with arrow) (R8-3gP), and X:XX AM TO X:XX PM (with arrow) (R8-3hP).</p>
</blockquote>
<p>These are the R8-3 and R8-3a signs to which the regulations refer:</p>

<p>There are other &quot;No Parking&quot; signs that indicate the beginning, end or continuation of prohibited parking zones.</p>
