We hereby provide an overview of the traffic signs used for road traffic and the procedure for using them.
Estonian Standard EVS 613 sets out eight groups of traffic signs:

  • danger warning signs
  • priority signs
  • prohibitory signs and signs having zonal validity
  • mandatory signs
  • special regulation signs
  • direction, position or indication signs
  • information, facilities or service signs
  • additional panels

The first number in the designation of a sign indicates the group of the sign, the second number indicates the subgroup, and the third (sometimes accompanied by a character) indicates the sequence in the subgroup, therefore indicating a single certain sign. The background colour of the sign is indicated by the respective attached characters, s – blue; v – white; and k – yellow. If all the signs of a subgroup have the same designation or a common feature of the signs is mentioned, the third number is omitted when referring to a single sign.
The signs are divided into four groups by size:

  • group 0 – very small;
  • group 1 – small;
  • group II – medium;
  • group III – large.

The sizes of the signs to be used will be chosen according to the requirements set out in the table. Signs of a smaller size may be replaced with signs of a bigger size. It is recommended to use signs of the same standard size within the limits of a single road or registered immovable.

Sign size group
Outside settlements In settlements
0 One-lane and multi-lane roads at the permitted vl speed, vp project speed or at the v85 speed up to 30 km/h One-lane and multi-lane roads at the permitted vl speed, vp project speed or at the v85 speed up to 30 km/h
I One-lane and multi-lane roads at 30 < vp project speed up to 60 km/h Roads at the permitted 30 < vl speed up to 50 km/h
II Roads with two and more lanes vp project speed over 60 km/h Roads with raised speed limits
III Motorways  -

 

  • The permitted vl speed is the speed limit established for the road.
  • The vp project speed is the highest safe speed of a single vehicle that serves as the basis for the main parameters of the road.
  • The v85 speed is the speed that 85% of the vehicles driving on the road do not exceed.

Retro-reflecting sheeting of class I is generally used for producing traffic signs and direction signs. Retro-reflecting sheeting of class II must be used for the following:

  • danger warning signs 111, 112, 121, 122, 131, 132, 137, 138, 171-176
  • priority sign 212
  • special regulation signs 534 and 544
  • signs to be installed above the carriageway.

It is also recommended to use retro-reflecting sheeting of class II for signs that are difficult to notice for drivers due to low visibility and local circumstances.
When designing signs with text (direction signs), the height of uppercase characters will be used as the basis, depending on the location of installation of the sign.
The height of uppercase characters will be chosen as follows for signs used outside settlements:

  • motorways and class I roads – 300 mm;
  • major highways – 200 or 300 mm;
  • main connecting roads – 150 or 200 mm;
  • secondary roads – 100, 125 or 150 mm;
  • local rural roads and private roads – 75 or 100 mm.

The height of uppercase characters will be chosen as follows for signs used in settlements:

  • streets with raised speed limits – 150 or 200 mm;
  • other streets depending on their importance and actual speed – 75, 100, 125 or 150 mm.

The height of uppercase characters of signs 635, 636 and 643 installed on class I roads, major highways and main connecting roads must be 150 mm. When such signs are installed on other roads, the height of uppercase characters will be chosen pursuant to the aforesaid list.

The height of uppercase characters of sign 644 (road name) must be 75 or 100 mm.
