The following list is borrowed from that, with additional commentary.

These definitions interact with each other, and affect many other sections of your GIs.
Be very careful changing them for a gimmick.
Usually it is easier (and safer) to base gimmicks on whether you use "execute" or "complete" elsewhere, rather than to gimmick the definition of one of these three terms.
 
<blockquote>
;INTERSECTION
:a location where two or more roads meet, where you can proceed in more than one direction excluding a U
:a location where two or more differently named roads meet
:a location where two or more differently named roads meet, where you can proceed in more than one direction excluding a U
</blockquote>
 
These are only a few of the more common variations on this definition, which doesn't do much by itself.
However, other definitions may specify actions that can be done only at intersections.


;AT:as close as possible, within 100 feet
The "differently named" condition will be affected by which words exist on signs.
;COMPLETE:execute or delete
Maple Ave and Maple Cir are differently named.
;CRI:Continue or begin working on the RI indicated and delete all lower numbered RIs, if any
But if Avenue, Circle, and their abbreviations do not exist on signs, then Maple and Maple are not differently named.
;CS:Continue Straight through one intersection
;DELETE:consider non-existent for rallye purposes
;DRI:Delete the RI in effect
;EXECUTE:physically do
;INTERSECTION:a location where two or more roads meet, where you can proceed in more than one direction excluding a U


This definition affects where you can "TURN", and so on. Often an intersection is limited to "differently named" roads, so that SMITH ST. and SMITH CT. may not be differently named (depending on which road type words are explicitly nonexistent from signs).
<blockquote>
;TURN
:change your direction of travel between 30 and 150 degrees [in an intersection]
:change your direction of travel approximately 90 degrees [in an intersection]
;L: turn to the Left [in an intersection]
;R:  turn to the Right [in an intersection]
;CS: Continue Straight [through one intersection]
</blockquote>


;L:    turn to the Left
These are usually fairly straight-forward, but gimmicks can be based on whether they must be done at intersections, and on the definition of an intersection.
;NLORBN:    No Longer On the Road By Name


This "turns off" an ONTO, described below.
<blockquote>
;CH:  a Chance to turn in the direction indicated
;PL:  a Place where you can turn in the direction indicated
;OPP: an Opportunity to turn in the direction indicated
</blockquote>


;ON:    physically upon
Common gimmicks include removing the "in the direction indicated" condition, or adding an "in an intersection" condition.
;ONTO:    on the road by name
Another is to define one of these (typically CH or PL), and then use one of the others (typically OPP, including the phrase, "Eh, what's Opp, Doc?" in the critique).
It is also possible to define more than one of these, setting up different gimmicks.


This definition lacks the important semantics of ONTO, which are typically described elsewhere, normally
<blockquote>
in the GI's Route section.  When completing an instruction including ONTO, you are to remain on that road until
;NLORBN: No Longer On the Road By Name
the correct trigger, which is typically being instructed NLORBN.  Many times, staying ONTO will require a U turn if the road changes its name.  The GIs should be explicit about whether you should U at a name change.
;ON:    physically upon
;ONTOon the road by name
</blockquote>


;OPP:    an Opportunity to turn in the direction indicated
The important semantics of ONTO are typically described in the Route section of the GIs.
Usually, executing (or completing) an instruction using ONTO puts you on the road by name.
When onto, you must remain on the road by that name until a designated trigger.
A common trigger is the NLORBN instruction.
(A common gimmick is a NLOBRN instruction.)
The GIs should explicitly state whether you should U to remain on the road by name.


Alternatives include CH ("a Chance...") and PL ("a Place...").

A signal is sometimes defined to be the ''intersection'' controlled by the electrically-operated control.
There are so many ways to twist rallyists expectations of what a SIGNAL or a STOP is.
An octagonal sign can be identified from the back.
Bus stop signs (as well as others) have the word "STOP" on them.
No Parking and Do Not Enter signs are red and white.
Modern yield signs are red and white, and control your forward progress.
CMs and CP signs may control your forward progress, if the GIs tell you to stop at them.


;STOP:    an octagonal sign with the word "STOP" on it
A common Q-A gimmick is to define one of these as an intersection, and then to ask what color it is.


If STOP is defined merely as an octagonal sign, it is identifiably from the front or back.  If it is

Revision as of 15:32, 31 July 2007

The following list was originally borrowed from our Sample General Instructions for a Coursemarker Gimmick Rallye. There is additional discussion at the end of this article.

Definitions

Commentary follows each group of definitions.

COMPLETE
execute or delete
DELETE
consider non-existent for rallye purposes
EXECUTE
physically do

These definitions interact with each other, and affect many other sections of your GIs. Be very careful changing them for a gimmick. Usually it is easier (and safer) to base gimmicks on whether you use "execute" or "complete" elsewhere, rather than to gimmick the definition of one of these three terms.

INTERSECTION
a location where two or more roads meet, where you can proceed in more than one direction excluding a U
a location where two or more differently named roads meet
a location where two or more differently named roads meet, where you can proceed in more than one direction excluding a U

These are only a few of the more common variations on this definition, which doesn't do much by itself. However, other definitions may specify actions that can be done only at intersections.

The "differently named" condition will be affected by which words exist on signs. Maple Ave and Maple Cir are differently named. But if Avenue, Circle, and their abbreviations do not exist on signs, then Maple and Maple are not differently named.

TURN
change your direction of travel between 30 and 150 degrees [in an intersection]
change your direction of travel approximately 90 degrees [in an intersection]
L
turn to the Left [in an intersection]
R
turn to the Right [in an intersection]
CS
Continue Straight [through one intersection]

These are usually fairly straight-forward, but gimmicks can be based on whether they must be done at intersections, and on the definition of an intersection.

CH
a Chance to turn in the direction indicated
PL
a Place where you can turn in the direction indicated
OPP
an Opportunity to turn in the direction indicated

Common gimmicks include removing the "in the direction indicated" condition, or adding an "in an intersection" condition. Another is to define one of these (typically CH or PL), and then use one of the others (typically OPP, including the phrase, "Eh, what's Opp, Doc?" in the critique). It is also possible to define more than one of these, setting up different gimmicks.

NLORBN
No Longer On the Road By Name
ON
physically upon
ONTO
on the road by name

The important semantics of ONTO are typically described in the Route section of the GIs. Usually, executing (or completing) an instruction using ONTO puts you on the road by name. When onto, you must remain on the road by that name until a designated trigger. A common trigger is the NLORBN instruction. (A common gimmick is a NLOBRN instruction.) The GIs should explicitly state whether you should U to remain on the road by name.

See also: Onto Gimmicks

SIGNAL
an electrically operated traffic control device, working or not
an intersection where traffic is controlled by electrically operated traffic control devices, working or not
STOP
an octagonal sign with the word "STOP" on it
a government-erected sign with the word "STOP" on it
a government-erected sign that controls traffic flow at an intersection
a government-erected red-and-white sign
a red-and-white sign that controls your forward progress
an intersection where traffic is controlled by [any of the above]

There are so many ways to twist rallyists expectations of what a SIGNAL or a STOP is. An octagonal sign can be identified from the back. Bus stop signs (as well as others) have the word "STOP" on them. No Parking and Do Not Enter signs are red and white. Modern yield signs are red and white, and control your forward progress. CMs and CP signs may control your forward progress, if the GIs tell you to stop at them.

A common Q-A gimmick is to define one of these as an intersection, and then to ask what color it is.

T
an intersection shaped like the capital letter T, approached up the stem

Be extremely careful if you make any changes to this definition (or to the definition of "SIDEROAD", if defined to be a T approached across the top). It is very easy for these definitions to apply more broadly than one might expect, which can make an interesting gimmick if you intended it that way, and which can cause problems if you didn't.

U
reverse your direction of travel

A "CYA" sentence in the GIs (typically under Route) instructs rallyists to "Make all U's at a safe and legal place, but consider them made where instructed." If the rallyist goes another block for a safe place to U, any signs or RMs seen in that block (in either direction) don't count for rallye purposes.

AT
as close as possible, within 100 feet
CRI
Continue or begin working on the RI indicated and delete all lower numbered RIs, if any
DRI
Delete the RI in effect

[Nothing to say?]

Discussion

A key question is which operations can be performed only at an intersection. Typical operations that may require an intersection are: L, R, TURN, CS (Continue Straight). U does not normally require an intersection; it is often needed at a dead end (cul-de-sac).

These definitions don't address the distinction between turning AT, ON, or ONTO. This is typical -- the distinction is normally clarified elsewhere in the General Instructions, normally in the Route section and/or Signs section.

It is typical that completing certain instructions to trigger an event, such as the activation of a NOTE instruction that follows a route instruction. Since complete is defined to mean execute or delete, an instruction might trigger the event twice -- once when executed, and again if later deleted (e.g., by a CRI)!

GIs often define additional abbreviations for brevity, but typically in sections other than Definitions, such as:

CM
Coursemarker
CP
Checkpoint
GI
General Instruction
RI
Route Instruction
RM
Rallyemaster
SI
Special Instruction
Supp
Supplemental Instruction
