Parking on the road and private traffic cones on a road in the UK
<p>Outside a private residence in the UK, the road is a slight curve and is narrow where 2 cars can only just get past each other. It is a road between two villages.</p>
<p>Is it legal to park a car there which can obscure traffic sight lines to the extent that some passing cars brake hard when there is oncoming traffic?</p>
<p>Is it legal to park a car on the curved road if there is a parking layby opposite the house which is offroad and has been used for 40 years?</p>
<p>Is it legal to park a car on a curved road which then causes traffic, including heavy buses, to use part of a neighbour's driveway for passing purposes which has caused the driveway to sink in one place?</p>
<p>Is it legal to put a traffic cone in front of and sometimes to the side of the car on the curved road which reduces road width further?</p>
<p>Note: I am aware of <a href="https://law.stackexchange.com/questions/64451/is-it-legal-to-put-a-traffic-cone-on-the-side-of-the-road-to-protect-property">this thread</a>, but that seems to be a little more specific for (building) property.</p>

<p>The OP's linked question seems to cover the placement of cones on the road.</p>
<p>The relevant legislation (from which some of the Highway Code derives its rules) and potential offences for the parking described are:</p>
<ul>
<li>Wilful obstruction, contrary to <a href="https://www.legislation.gov.uk/ukpga/1980/66/section/137?timeline=false" rel="nofollow noreferrer">section 137</a>, Highways Act 1980:</li>
</ul>
<blockquote>
<p>(1) If a person, without lawful authority or excuse, in any way wilfully obstructs the free passage along a highway he is guilty of an offence and liable to a fine not exceeding level 3 on the standard scale.(<a href="https://www.sentencingcouncil.org.uk/explanatory-material/magistrates-court/item/fines-and-financial-orders/approach-to-the-assessment-of-fines-2/9-maximum-fines/" rel="nofollow noreferrer"><em>i.e. £1,000</em></a>)</p>
</blockquote>
<p>And</p>
<ul>
<li>Leaving vehicles in dangerous positions contrary to <a href="https://www.legislation.gov.uk/ukpga/1988/52/section/22?timeline=false" rel="nofollow noreferrer">section 22</a>, Road Traffic Act 1988:</li>
</ul>
<blockquote>
<p>If a person in charge of a vehicle causes or permits the vehicle or a trailer drawn by it to remain at rest on a road in such a position or in such condition or in such circumstances as to involve a danger of injury to other persons using the road, he is guilty of an offence. (<a href="https://www.legislation.gov.uk/ukpga/1988/53/schedule/2/part/I?timeline=false" rel="nofollow noreferrer"><em>also £1,000 maximum fine</em></a>)</p>

<p>Answering one of multiple questions about curved roads:</p>
<blockquote>
<p>Is it legal to park a car there which can obscure traffic sight lines to the extent that some passing cars brake hard when there is oncoming traffic?</p>
</blockquote>
<p>The <a href="https://www.gov.uk/guidance/the-highway-code/waiting-and-parking-238-to-252" rel="nofollow noreferrer">Highway Code</a> rule 243 says</p>
<blockquote>
<p><strong>DO NOT stop or park:</strong></p>
<ul>
<li>. . .</li>
<li>on a bend</li>
<li>. . .</li>
</ul>
</blockquote>
<p>and other places where you would be causing an obstruction. Where the Highway code says &quot;DO NOT&quot; or &quot;MUST NOT&quot; this is a legal requirement (otherwise is says &quot;<em>should</em> not...&quot;).</p>
