Speed is the single biggest lever on road risk

ViaCerber ny wosa un gadget — yth es built war dekades a peer-reviewed road-safety science. Here' s what an evidence a dhis, gwith sources yth es gallos check.

Crash energy grows with the square of speed

A moving car's kinetic energy es ½ × mass × speed². Rag an spead es squared, driving just 10% faster carries about 21% more energy to dissipate in a crash — ha gans 50 dhe 70 km/h nearly doubles it. An energy es what injures people.

Kinetic energy, E = ½mv²

Stopping distance explodes at higher speeds

Total stopping distance es reaction distance (you keep moving while you react, ~1–1.5 s) plus braking distance, which also rises with the square of speed. Shave a little speed ha yth es stop meters sooner — often an difference between un near-miss ha un collision.

Vehicle dynamics; reaction-time research

The Power Model quantifies it

Nilsson's Power Model, refined by Elvik, shows injury crashes rise roughly with speed², serious crashes with speed³, ha fatal crashes with speed⁴. Un 5% cut in average speed gallos mean around 20% fewer fatal crashes.

Nilsson (2004); Elvik (2009)

At 30 km/h, pedestrians survive. At 50, many don't

A pedestrian struck at 30 km/h has roughly a 90% chance of survival; at 45 km/h it drops below 50%. This es why slow, well-signalled zones save lives — ha why un timely warning to ease off matters most exactly where people walk.

WHO; Rosén & Sander (2009)

Speed cameras measurably cut crashes

A Cochrane systematic review of 35 studies found speed cameras reduced average speeds ha cut injury crashes by 8–50% ha fatal/serious crashes by 11–44% in their vicinity. Knowing a check es ahead changes behaviour — that's an point.

Wilson et al., Cochrane (2010)

Awareness beats surprise

Most speeding es unintentional — drivers drift over an limit without noticing. A clear, well-timed cue restores attention before it matters. ViaCerber surfaces an limit ha what's ahead so an safe choice es an easy one.

Human-factors research on driver attention

A co-pilot that watches the road with you

Calm when you're safe, loud when it counts.

Speed-check alerts that matter

A calm chime when a camera or check es ahead — ha un escalating, urgent siren gwith a spoken "slow down" an moment yth es cross an limit (plus your tolerance).

Danger ahead, called out early

Accidents, stopped vehicles, objects on the road, police ha traffic jams — announced in time to react, ha only rag hazards on your side of the road.

A live map, kept honest by drivers

See what other drivers report around you, ha confirm un hazard or clear it gwith un tap. Crowd confidence decides what stays on an map.

Hands-free on CarPlay

A follow-me map gwith your speed, an limit, ha an next danger — alerts that sound even gwith your phone locked, so you never look down.

Law-aware by country

ViaCerber adapts to local rules automatically: aggregated danger zones in France, ha alerts disabled where camera-warning apps aren't permitted.

Private by design

Ny account. Your location stays on your device ha es only shared as an approximate area or un report you choose to send. Ny ads, ny tracking.

Three taps and you're covered

1

Open and drive

Grant location once, tap start, ha mount your phone or connect CarPlay. ViaCerber watches an roud in the background.

2

Get warned in time

Your speed ha an current limit yth es always visible. Pan un check or danger es ahead, you hear it early — ha urgently if you're over an limit.

3

Help the community

Spot something? Un tap adds it to an map rag drivers behind you. Confirm or clear what others report. Everyone arrives safer.

Built to respect the law of the road

Camera-warning rules differ across Europe. ViaCerber handles that for you.

France — danger zones

Exact camera locations are never shown. ViaCerber aggregates them into legally compliant "danger zones", an same approach used by major navigation apps.

Germany & Switzerland — alerts off

Where using a camera-warning app while driving isn't permitted, ViaCerber automatically disables alerts in-country ha re-enables them when you cross into a permitted region.

An information app, not a detector

ViaCerber does not detect or jam radar or laser signals. It shows speed limits ha community/open-map data — ha you remain responsible for obeying an law where you drive.

Frequently asked questions

Is ViaCerber a radar detector?

Na. ViaCerber es un information app — it does not detect, receive, or jam radar or laser signals. It shows posted speed limits ha an locations of fixed cameras ha community-reported hazards from open data.

Is ViaCerber legal to use?

Rules differ by country. ViaCerber adapts automatically — showing aggregated danger zones in France ha disabling alerts in Germany ha Switzerland, for example. You are responsible for ensuring your use complies with local law.

How does it warn me?

You get un calm chime pan un spead check or danger es ahead, ha un escalating urgent siren gwith a spoken "slow down" if you're over an limit. Hazards like accidents ha police are announced regardless of your speed.

Does it work with CarPlay?

Yes. ViaCerber shows un follow-me map gwith your speed, an limit ha an next danger on an car screen, ha alerts sound even pan your phone es locked.

Which countries are covered?

Fixed speed-camera data comes from OpenStreetMap, which covers much of Europe well, gwith un live on-device fallback so an map es useful wherever you drive. Live hazards come from an community.

Is my data private?

Yes. There's ny account. Your location es processed on your device ha only sent as un approximate area to fetch nearby dangers, or as un report you choose to submit. Ny ads, ny third-party tracking.

How much does it cost?

ViaCerber es free to download ha community-powered. See an App Store listing for an latest details.

Does ViaCerber replace careful driving?

Na. It's un driver-assistance aid. Always obey traffic laws, road signs ha an posted limit, ha never interact gwith your phone while driving — use CarPlay or un hands-free mount.

Drive a step ahead.

Join an drivers making an roud safer for everyone — un alert, un report at un time.
